  • Effect of Addition of Grain Refiner and Modifier on Microstructural and
           Mechanical Properties of Squeeze Cast A356 Alloy

    • Free pre-print version: Loading...

      Abstract: Al-Si alloy of grade A356 is widely used in several industries such as automobile, aerospace, defense, and others owing to its low density as well as the combination of other properties such as high strength, excellent castability, excellent thermal conductivity, good corrosion resistance, and good wear/abrasive resistance. In previous studies, the mechanical properties of gravity die-cast Al–Si alloys were found to be improved by the addition of grain refiners such as boron and titanium and also with the addition of modifiers such as strontium. Squeeze casting is pressure-assisted casting process and has been found to improve the mechanical properties of Al alloys. In the current study, the effect of the addition of Al-Ti-B alloys used with the purpose of grain refinement as well as the effect of combined additions of Al-Ti-B and two Sr levels used with the purpose of microstructural modification in squeeze cast Al–Si alloy A356 are investigated. The microstructure developed in various alloy compositions of squeeze cast alloys and the mechanical properties are studied. The effect of T6 solution heat treatment on the squeeze cast alloys is also analyzed. The addition of grain refiner and modifier helped in improving the mechanical properties of the alloy and further heat treatment helped in increasing the properties of the alloy.

  • Effects of Specimen Size, Strain Rate and Temperature on the Deformation
           Behaviors at Micro-/Mesoscale in Ultrafine-Grained Pure Zr

    • Free pre-print version: Loading...

      Abstract: An ultrafine-grained pure (UFG) zirconium (Zr) prepared by the equal channel angular pressing (ECAP) + rotary swaging composite refining process was annealed at 473 K, 573 K, 623 K and 673 K, respectively, to obtain different grain sizes. In addition, micro-compression testing was conducted with the specimen diameters of 4.0, 2.0 and 1.0 mm at elevated temperature and the strain rates of 0.002 s−1 and 0.01 s−1, respectively. According to the results, the micro-hardness of the specimens annealed at 573 K was significantly higher than that of the specimens annealed at 473 K, showing a significant annealing strengthening effect. It is found that the flow stress decreases with the decrease in the specimen size during micro-compression of the UFG pure Zr. Furthermore, the increase in the grain size lead to the increase in the flow stress which then decreases before increasing again, demonstrating that UFG pure Zr exhibits the grain size effect of micro-/meso-forming. The UFG pure Zr has strong temperature dependence and high strain rate sensitivity, while the former is significantly stronger than the latter. This study can further investigate the effect of different process parameters on the micro-plastic forming of UFG pure zirconium and promote the development of micro-forming processes.

  • Microstructural Characterization and Hardness Study of Nanostructured
           CoCrFeNi High Entropy Alloys with Dual Effect of Y and Nano-Sized Y2O3
           Additions

    • Free pre-print version: Loading...

      Abstract: The motivation of this work is to increase the grain size stability of nanocrystalline CoCrFeNi high entropy alloys (HEA) with Y and Y2O3 additions to strike a balance between thermodynamic and kinetic stabilizations. The nanocrystalline HEAs prepared by mechanical alloying were annealed at different temperatures and characterized by X-ray diffraction, focused ion beam microscopy and micro-hardness test. The results revealed that as-milled nanostructured grain size yielded grain growth upon annealing reaching to 350 nm and 1.3 μm after annealing at 900 °C and 1100 °C, respectively, while the addition of Y and Y2O3 appeared to stabilize the grain size in the nano-range after annealing at the same temperatures. Consequently, while the as-milled hardness of CoCrFeNi HEA dropped from 475 HV to around 200 HV after annealing at 1100 °C, the elevated hardness of 430 HV was retained with Y and Y2O3 additions after annealing at the same temperature.

  • Processing and Characterization of Al-4Cu Matrix Composites Reinforced
           with Few Layered Graphene

    • Free pre-print version: Loading...

      Abstract: Few-layered-graphene (FLG)-reinforced Al-4 wt.% Cu matrix composites were produced via the powder metallurgy (PM). FLG was incorporated into the matrix via a mechanical alloying (MA) process conducted for 5, 7 and 9 h in a planetary ball mill. The mechanically alloyed (MA’ed) powders were consolidated by uniaxial pressing and pressureless sintering. Properties of the Al-4Cu-xFLG composites were examined via Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), Optical Microscopy (OM), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDX), Archimedes method, microhardness, compressive and wear tests. According to the mechanical characterization, FLG addition relatively improved the hardness, whereas it caused the decline of compressive strength. However, the specific wear ratio of the same sample increased by two times compared to the Al-4Cu.

  • Effect of Powder Characteristic and Aging Treatment on the Corrosion
           Behavior of Selective Laser Melted Al-20Si Alloy

    • Free pre-print version: Loading...

      Abstract: Hypereutectic Al-20Si alloy is widely used in automotive, aerospace, and other fields because of its lightweight, high thermal conductivity, good wear, and corrosion resistance. In this study, the effects of powder characteristics and aging treatment on the corrosion behavior of Al-20Si alloy prepared by selective laser melting (SLM) were systematically investigated. The results showed that the Al-20Si alloy synthesized with ball-milled powders (BMPs) presents a large number of pores and coarse Si particles, while the Al-20Si alloy prepared with atomized powders (APs) shows a uniform and dense microstructure with relatively small grain sizes. The Si phase was continuously precipitated and coarsened with increased aging temperature. Moreover, the fibrous eutectic Si prepared with APs was transformed to a particulate shape. The alloy manufactured with APs shows excellent corrosion resistance. Meanwhile, with the increase of aging treatment temperature, the corrosion resistance of the alloy was significantly reduced.

  • Application of Artificial Neural Network to Predict the Hot Flow Behavior
           of Ti-Nb Microalloyed Steel During Hot Torsion Deformation

    • Free pre-print version: Loading...

      Abstract: In the present study, the hot compressive deformation behavior of Ti-Nb bearing microalloyed steel was investigated in the temperature range of 850–1100 °C and strain rates of 0.01–1 s−1. Flow curves obtained from hot compression tests were analyzed, and it was demonstrated that dynamic recrystallization is the main softening mechanism during deformation at 900, 1000, and 1100 °C at all strain rates. It was also demonstrated that dynamic recovery occurs during deformation at 800 °C. Based on the obtained results, an artificial neural network was constructed to predict the hot flow softening behavior of Ti-Nb microalloyed steel which is due to the occurrence of dynamic recrystallization and recovery. Results obtained from artificial neural network were compared with the experimental values of flow stress, and a very good correlation was observed between them. This indicates the excellent capability of the developed artificial neural network to predict the flow softening due to complex microstructural evolutions accompanying dynamic recrystallization and dynamic recovery.

  • Dry Sliding Wear Behaviour of Epoxy/Biochar Composites

    • Free pre-print version: Loading...

      Abstract: Traditional method of production of carbon black is very expensive. Recent focus of researchers worldwide is to produce carbon black from agricultural waste products and from some lignocellulosic biomass that is rich in organic materials. In this present study, carbon black is prepared from a biowaste material known as wood apple shell and utilised as reinforcement material in epoxy with filler loading of 5,10,15, and 20 weight percent. Carbon blacks were produced with different carbonisation temperature (400,600 and 800 ℃). Dry sliding wear behaviour of the developed composites was studied. The wear studies with different load and sliding velocities indicate that 10 weight percent of filler loading with carbon black produced with 800 ℃ gives least material removal rate. Surface of wear out composites was studied with FESEM and the dominating wear mechanism was discussed.

  • Microstructure of Commercial-Purity Aluminum Sheets Processed by
           Accumulative Roll Bonding (ARB) at a Series of Cyclic Preheating
           Conditions

    • Free pre-print version: Loading...

      Abstract: The high production efficiency, energy-saving characteristics, and universal applicability of accumulative roll bonding (ARB) in the field of commercial aluminum sheets fabrication are well recognized. However, microstructure characterization driven by processing parameters still needs optimization. The purpose of this study is to investigate the effect of cyclic preheating parameters on the microstructure of commercial purity aluminum sheets processed by six cycles of ARB. Specifically, a series of cyclic preheating conditions set as A: 523 K-1200 s, B: 573 K-300 s, and C: 573 K-1200 s was repeatedly applied, and differences among these three sample groups in microstructure and mechanical properties were discussed by comparing their scanning electron microscopic (SEM) pictures, orientation image maps (OIMs), Vickers hardness, and tensile strength. It was found that B: 573 K-300 s was the critical condition for sheets with both stable bonding state and ultrafine grains (UFGs). This study provides a reference for selecting cyclic preheating and reveals microstructural characteristics of ARB processed commercial-purity aluminum sheets.

  • Two Stage Quench Partitioning Studies with Versatile Microstructures and
           Mechanical Properties

    • Free pre-print version: Loading...

      Abstract: Abstract Two stage quench partitioning was carried out on steel with 0.2%C, 1.35%Si, 1.7% Mn microalloyed with Nb and Ti. The austenitization temperatures were varied to obtain 0 to 57% intercritical ferrite. The remained austenite was quenched to create martensite and residual retained austenite that was about 20%, 40% and 80% of the original austenite and held for long enough (15 min) to create single stage quench partitioning. This was followed by second stage quenching at temperatures between 400 and 450 °C where the residual austenite was transformed to bainite. The steels show excellent tensile strength (827 to 1149 MPa) and elongation (14 to 26%) with product of tensile strength and elongations exceeding 20 GPa%, in some of the conditions qualifying for third generation advanced high strength steel. Microstructural analysis and X-ray diffractions were carried out to identify the phases responsible for excellent combination of strength and ductility.

  • Dynamic Recrystallization and Dynamic Precipitation in AA6061 Aluminum
           Alloy During Friction Stir Welding

    • Free pre-print version: Loading...

      Abstract: Abstract This paper investigated the mode of recrystallization in the nugget zone (NZ) of friction stir welding (FSW) joint of AA6061-T6. By correlating grain orientation spread results, kernel average misorientation (KAM) results, misorientation maps of grain boundaries (GBs) and selected area diffraction patterns of precipitates systematically, we found that continuous dynamic recrystallization (CDRX) and geometric dynamic recrystallization (GDRX) both occurred. CDRX could be enhanced by decreasing feeding speed of FSW. The variation trend of fraction of low-angle grain boundaries in NZ indicated different contribution brought by CDRX and GDRX and also different combination form of heat input. KAM results can also act as indicator of the extent of dynamic recrystallization in the NZ of FSW, only under a constant feeding speed. The fine needle-shaped β'' precipitate disappeared in NZ and evolved to β' and equilibrium β-Mg2Si phase during FSW. Furthermore, the shape and orientation of β' or β phases could be changed by mutual interaction with dislocation movement, to different extent depended on CDRX.

    • Free pre-print version: Loading...

      Abstract: Abstract Comprehensive characterization studies are carried out to develop a suitable beneficiation process for treating low-grade platinum group elements (PGEs) ore from Mesoarchean Boula-Nuasahi Igneous Complex in southern part of Singhbhum Craton, eastern India. The PGE mineralization is magmatic and hydrothermal in origin and found in association with NNW–SSE-trending mafic–ultramafic igneous rocks in the tectonic brecciated zone toward the eastern part of the complex. The PGE-bearing minerals are very fine grained (< 1–50 µ) and exhibit heterogeneous distribution, with a total grade of 2.094 g/t. Chalcopyrite, pyrrhotite, pentlandite, pyrite, etc. are found as discriminate grains while the altered silicates (tremolite, riebeckite, enstatite, etc.) are the main gangue minerals present in this ore. The common PGE minerals, such as sperrylite, sudburyite, braggite, laurite, and testibiopalladite, are identified, and individual elemental distribution is analyzed by electron probe micro-analyzer mapping. Based on the studies, different flow schemes are proposed and discussed.

  • CO2 Emission of CO2 Injection into Blast Furnace

    • Free pre-print version: Loading...

      Abstract: Abstract As an energy-intensive industry, the iron and steel industry has been facing the challenges associated with reducing CO2 emissions. Therefore, metallurgical workers have been examining whether the steel industry can absorb some of the CO2 emissions. At high temperatures, CO2 is capable of oxidizing, which can lead to reactions with the carbon in the tuyeres raceway of the blast furnace to generate twice the volume of CO, improving the degree of indirect reduction and increasing the CO concentration in the top gas. In this study, metallurgical thermodynamics is used as the basis for constructing mathematical models of the mass and energy balance of a blast furnace and of the heat balance of a hot blast stove. Based on these models, the CO2 emission of CO2 injection into blast furnace is analyzed using the blast furnace CO2 emission model. Because of the endothermic reaction between CO2 and carbon, thermal compensation for the increases in the fuel ratio and oxygen enrichment is required. As the CO2 enrichment rate increases, the input of CO2 emission increases. However, as the CO concentration in the top gas increases and the top gas required by the hot blast stove decreases, the CO2 emission reduction at the output increases. When the CO2 enrichment limit is reached, the CO2 emission at the input increases by 530.97 kg/(tHM), the CO2 emission reduction at the output increases by 544.65 kg/(tHM), and the net CO2 emission decreases by 13.68 kg/(tHM). The high-quality top gas can replace a portion of the role of gas producers and reduce the CO2 emission of gas producers by 38.84 kg/(tHM). It can also prevent too much low-quality top gas from being released.

           Phosphors Deposited by Friction Stir Processing

    • Free pre-print version: Loading...

      Abstract: Abstract The goal of this study is to examine the thermoluminescence (TL) properties of materials obtained by depositing rare earth ion-doped yttrium stannate (Y2Sn2O7) phosphor powders on metallic surfaces using friction stir technique. Y2Sn2O7 phosphors doped with Tb, Eu and Dy rare earth ions were produced by the solid-state reaction synthesis method by sintering at 1450 °C. TL properties of Y2Sn2O7:Eu, Dy and Tb were examined under X-ray irradiation, UV radiation (254 nm) and beta radiation. Thermoluminescence dosimeter (TLD) reader was used for recording the TL glow curves, and linear heating rate was selected as 2 Ks−1. The thermoluminescence glow curves of deposited phosphors showed prominent glow peaks at 225 °C for Y2Sn2O7:Tb, 185 °C and 295 °C for Y2Sn2O7:Eu and 150 and 260 °C for Y2Sn2O7:Dy after irradiated with X-ray radiation. TL properties of phosphor composites deposited by friction stir processing are a pioneering study.

  • Influence of Shielding Gas Composition and Pulsed Current Frequency on the
           Microstructure of Austenitic Stainless Steel Welded by Pulsed Current GTAW
           

    • Free pre-print version: Loading...

      Abstract: In the current research, an attempt was made to study the effect of shielding gas composition and operational parameters on the microstructure of austenitic stainless steel. Fulfilling this purpose, a 4 mm austenitic stainless steel sheet was provided. Pulsed current gas tungsten arc welding was carried out using nitrogen gas with the volume percent of zero, 0.5, 1, 2, 5, and 10 in addition to argon as the shielding gas and under pulsed current with frequencies of 40, 80, 120, 160, and 200 Hz. After welding, samples were cut, and the metallographic study was done on weld metal by optical microscope and scanning electron microscope. Furthermore, a ferrite-scope test was performed on the weld metal, and the results were evaluated. Mechanical properties were investigated, and fracture surface was studied. Results showed that increasing the frequency of pulsed current leads to a decrease in ferrite amount in the microstructure, and the area fraction of ferrite decreased to 23% by increasing the frequency. Moreover, it was proven that the addition of nitrogen to the shielding gas resulted in an ascending change in the heat input in the weld pool. Also, with the increase in welding metal nitrogen, ferrite at frequencies of 40 and 200 Hz decreased to 56% and 62%, respectively. In addition, the morphology of the remaining ferrite transformed from mixed lacy-vermicular to completely vermicular. The hardness of the weld metal increased to 66% and 37% at the frequencies of 40 and 200 Hz, respectively. Similarly, the yield strength increased to 11% and 10% at similar frequencies.

  • Optimal Control of Surface Crack in Microalloyed Steel with Big Stroke
           Liquid Core Reduction Process

    • Free pre-print version: Loading...

      Abstract: Abstract In this paper, a new idea of optimizing and improving the surface crack of microalloyed steel slab by using big stroke liquid core reduction (B-LCR) process was studied and analyzed by combining numerical simulation with industrial test. The results show that the stress–strain distribution is different in different parts of the slab during liquid core reduction; the stress at the corner of the slab is the largest, and the stress at the wide surface is greater than that at the narrow surface. When the total reduction is increased to 35 mm by using B-LCR process, the equivalent strain on the interior of the slab is 0.566%. It is consistent with the maximum additional strain value (calculated value) of 0.552% on the center of the slab, and no pressure crack will occur. The industrial test results show that B-LCR process can improve the internal and surface quality of low content alloying element steel obviously. But with the gradual increase in microalloying element content, B-LCR process cannot completely solve the surface crack defect. It can only play a role in reducing defects.

  • Optimization of Column Flotation for Fine Coal Using Taguchi Method

    • Free pre-print version: Loading...

      Abstract: Abstract The efficacy of column flotation in producing low-ash clean coal for the metallurgical industries is explored in this work. The effect of four critical operating parameters such as collector dosage (A), frother dosage (B), superficial velocities of air (C) and wash water (D) on the combustibles recovery (CR) and ash rejection (AR) was studied. Experiments were carried out based on the Taguchi orthogonal array of experimental design ( \(L_{9} OA\) ), and the signal-to-noise (S/N) ratios were calculated for both the responses. In this study, the principal parameters, their rank on the responses and the optimum conditions to maximize the responses were also identified. Column flotation produced clean coal with combustibles recovery in the range of 66.94–80.04%, while keeping the ash rejection in the range of 55.91–73.83%. Regression models were developed to predict the separation efficiency, ash rejection and combustible recovery in the column flotation, and the average error in prediction of the separation efficiency was ± 6%.

  • Resistance Spot-Welded Dissimilar Sheets—Parametric Behavioral Analysis
           using Experimentation and Simulation

    • Free pre-print version: Loading...

      Abstract: Abstract This study focuses on joining stainless steel (SS) 316L and duplex stainless steel (DSS) 2205 sheets of 2 mm thickness using the resistance spot welding (RSW) process. The welding parametric values observed to be appropriate for fabricating a quality weld nugget are: welding current of 9 kA, electrode tip of diameter 6 mm, and welding time of 9 cycles. The weld joint fabricated using the selected parameters yielded a maximum weld nugget strength of 17.6 kN and tensile shear strength of 352 MPa. A two-dimensional axisymmetric model based on coupled thermal–electrical–structural analysis was implemented using ABAQUS-2017 software to simulate the RSW process. Temperature profile, weld nugget shape, deformation, and the evolution of stress and strain were predicted with a finite element (FE) model. A three-dimensional explicit FE model replicating the experimental tensile shear test was demonstrated. The predicted results and the actual fracture behavior showed good coherence. The FE-predicted and experimental results were validated for the weld nugget geometrical profiles and tensile shear strength showed good agreement with negligible deviations.

  • A Study on the Suitability of Mahanadi Riverbed Sand as an Alternative to
           Silica Sand for Indian Foundry Industries

    • Free pre-print version: Loading...

      Abstract: Abstract The availability of silica sand is diminishing and as a result, the price of silica sand increasing. Therefore, there is a need to evaluate the suitability of local riverbed sand for nonferrous alloy casting in Indian foundries. The present investigation focuses on the suitability of Mahanadi Riverbed Sand (MRS) for nonferrous alloy casting. The sand particle size, chemical composition, density, and fusion point, are evaluated and found suitable for nonferrous alloy casting. The mold ingredients are designed and optimized through the design of the experiment and response surface methodology, respectively. It is found that 11.5 wt.% of bentonite clay, 5 wt.% of moisture, and 3.5 wt.% of coal dust is suitable to achieve the desire sand mold properties. The fusion point of MRS shows that it is not suitable for ferrous casting. Therefore, aluminum alloy (A356) casting is performed using MRS and silica sand mold. The as-cast surface roughness (Ra), hardness, and microstructures of A356 alloy casting are evaluated and compared between MRS and silica sand mold castings. It is observed that the mechanical properties of MRS mold casting are better than silica sand mold casting and may be used as an alternative to silica sand for aluminum alloy casting in Indian foundry industries.
