  • Investigation on Reaction Interface between the Aluminum and K 2 ZrF 6 by
           Freezing the Molten Salt Reaction
    • Authors: Qing-Feng Zhu; Fei Li; Lei Li; Wen-Jing Wang; Gao-Song Wang; Jian-Zhong Cui
      Pages: 433 - 437
      Abstract: A reaction interface between the aluminum and K2ZrF6 during molten salt reaction process was frozen by quenching the mold in water, and the interface structure was analyzed to determine the formation process of Al3Zr. Results show that a clear conical interface existed between the K2ZrF6 and aluminum. A zirconium accumulation layer with the thickness of about 2–3 μm was formed at the aluminum side of the interface. Many initially formed Al3Zr particles (with the size of 0.4–16 μm) distributed in this layer, most of which located at the interface. The morphology of Al3Zr particles is closely related with their size. For the size of 0.4–1 μm, the Al3Zr appeared as globular and ellipsoid shapes. When it grew to the size of 1–2 and 2–16 μm, it exhibited the rule cube shape, and rule cuboids shape, respectively.

  • Correlation Between Microstructure and Mechanical Properties of 2219-T8
           Aluminum Alloy Joints by VPTIG Welding
    • Authors: Lan-Qiang Niu; Xiao-Yan Li; Liang Zhang; Xiao-Bo Liang; Mian Li
      Pages: 438 - 446
      Abstract: In this study, 2219-T87 aluminum alloys were butt welded by the double-pass tungsten inert gas arc welding process. And the softening behavior of fusion zone (FZ) and heat-affected zone (HAZ) was evaluated with the analysis of welding temperature field, grain size, alloying element distribution and precipitates evolution. Results show that the two FZs are almost the weakest regions in the joint, where the microhardness value is 76 and 78 HV, respectively. Microhardness of the HAZ generally grows along with increasing distance from fusion line except a valley value at the distance of about 4.5 mm. The mean grain size of two FZs is about 74.4 and 79.2 μm, whereas 41.5, 44.9 and 43.4 μm for the two measured HAZs and base metal (BM), respectively. There is about 60.4% and 54.2% Cu consumed in the coarse whitish particles of FZs that have little strengthening effect, while the percentage is about 24.6% of BM that is almost the same as HAZ. A large number of strengthening phases θ′ distribute dispersively in BM, whereas hardly any precipitates exist in FZ and HAZ adjacent to FZ. So the coarsening of grain size, reduction and segregation of alloying element content, and the precipitate evolution are regarded as the main causes of softening in FZ, while the precipitate evolution is the main factor of softening in HAZ.

  • Electrical Discharge Machining of Al2024-65 vol% SiC Composites
    • Authors: Wen-Shu Yang; Guo-Qin Chen; Ping Wu; Murid Hussain; Jia-Bing Song; Rong-Hua Dong; Gao-Hui Wu
      Pages: 447 - 455
      Abstract: In the present work, the wire electrical discharge machining (WEDM) process of the 65 vol% SiCp/2024Al composite prepared by pressure infiltration methods has been investigated. The microstructure of the machined composite was characterized by scanning electron microscope, the average surface roughness (Ra), X-ray diffraction, X-ray photoelectron spectroscopy and transmission electron microscopy (TEM) techniques. Three zones from the surface to the interior (melting zone, heat affected zone and un-affected zone) were found in the machined composites, while the face of SiC particles on the surface toward the outside was “cut” to be flat. Increase in Al and Si but decrease in C and O were observed in the core areas of the removed particles. Si phase, which was generated due to the decomposition of SiC, was detected after the WEDM process. The irregular and spherical particles were further observed by TEM. Based on the microstructure observation, it is suggested that the machining mechanism of 65 vol% SiCp/2024Al composite was the combination of the melting of Al matrix and the decomposition of SiC particles.

  • Effect of Open Porosity of Y 2 O 3 Ceramic on the Apparent Contact Angles
           and Interactions Between Ti47Al Alloys and Y 2 O 3 Ceramic
    • Authors: Chao Ran; Hua-rui Zhang; Hu Zhang; Bei-bei Wan; Peng Bai
      Pages: 456 - 463
      Abstract: The effect of open porosity of Y2O3 ceramic on the apparent contact angle and interaction between molten Ti47Al alloy and Y2O3 ceramic substrates under pure Ar was investigated by using a sessile drop method at 1600 °C. As the open porosity increased from 9.6% to 30.3%, the spreading rate of molten Ti47Al alloys on Y2O3 ceramic substrates reduced from 2.3 to 1.1°/s; meanwhile, the final equilibrium contact angles increased from 55.8° to 63.6°. The microstructure observations revealed that with increasing the open porosity of the Y2O3 substrates, the thickness of sand adhesion at the interfaces of the alloy droplets increased from 5.4 to 15.7 μm, and ceramic particles in the alloy matrix increased as well. The increasing contact area between the molten alloy and the substrate played a dominant role in determining the interaction on TiAl/Y2O3 interface.

  • Spheroidizing Behavior and Spheroidizing Kinetics of W-phase During
           Solid-Solution Treatment in Mg–Zn–Y–Mn–(B) Alloys
    • Authors: Kai Yang; Jin-Shan Zhang; Xi-Mei Zong; Wei Liu; Chun-Xiang Xu
      Pages: 464 - 469
      Abstract: The spheroidizing mechanism of W-phase in the Mg–Zn–Y–Mn–(B) alloys during solid-solution treatment was investigated by using kinetic methodologies. The microstructure and mechanical properties of heat-treated Mg94Zn2.5Y2.5Mn1 alloy containing 0.003 wt% B were compared with heat-treated Mg94Zn2.5Y2.5Mn1 alloy. The heat-treated Mg94Zn2.5Y2.5Mn1 alloy with 0.003 wt% B contained fine and uniform W-phase particles, which exhibited optimal mechanical performance. The ultimate tensile strength, yield strength and elongation were 287.7, 125.5 MPa and 21.1%, respectively.

  • Stress and Springback Analyses of API X70 Pipeline Steel Under 3-Roller
           Bending via Finite Element Method
    • Authors: Wenbo Zhao; T. Warren Liao; Lampros Kompotiatis
      Pages: 470 - 482
      Abstract: 3-Roller bending is a widely applied manufacturing process, particularly in structural steel pipe industry. However, due to the difficulty and high cost of measuring stress distribution inside sheet material via traditional method, internal stress/strain response during forming is largely unexplored. The focuses of this study are two: (1) to map the radii of curvature as well as the stress inside the work piece during forming by utilizing the meshing mechanism of finite element method, and (2) to further provide some numeric guidelines for the configuration of the rolling system in order to improve production efficiency and product quality. The results of this study indicate that: (1) it is crucial to properly choose forming parameter in order to produce product with desired radii; (2) much like a gradual springback process, the radii of curvature gradually increase from the top roller to the exit-side bottom roller; (3) under the assumptions made in this study, to produce pipes with a specified diameter with varying configurations of the 3-roller system will not significantly change the final residual stress; and (4) finally, shifting of the neutral axis up to 2.0% of the thickness toward the compressing side during the forming process is observed.

  • Effects of Cooling Paths on Through-Thickness Microstructure and
           Mechanical Properties of Heavy Gauge X80 Pipeline Steel
    • Authors: Xu-Dong Li; Cheng-Ning Li; Guo Yuan; Guo-Dong Wang
      Pages: 483 - 492
      Abstract: The effects of various cooling paths on uniformity of through-thickness microstructure and mechanical properties of X80 pipeline steel of 22.0 mm in thickness were studied. The finite difference method was employed to calculate the temperature field during cooling. It was confirmed by the experimental result and temperature field calculation that the optimizing process was achieved by the ultra-fast cooling with medium cooling capacity (cooling rate of ~23 K/s) followed by ultimate cooling capacity (cooling rate of ~50 K/s). After optimization, the experimental steel displayed much uniform microstructure and the deviation of through-thickness hardness was controlled within 20 HV. In addition, the yield strength, tensile strength and elongation of the experimental steel were 621, 728 MPa and 21.5%, respectively, meeting the requirements of the API standard for X80 pipeline steels.

  • Tailoring Microstructure and Tribological Properties of Cold Deformed
           TiZrAlV Alloy by Thermal Treatment
    • Authors: Guo-Sheng Zhang; De-Feng Guo; Ming Li; Jing-Tao Li; Qian Zhang; Xiao-Hong Li; Xiang-Yi Zhang
      Pages: 493 - 498
      Abstract: Microstructure evolution and tribological properties of a new TiZrAlV alloy have been investigated in the present study. Various microstructures, i.e., equiaxed grain structure, dual-phase lamella structure, and heterogeneous lamellar structure, have been successfully prepared, and the effect of the microstructure on tribological properties was explored by means of cold severe plastic deformation combined with subsequent recrystallization annealing and aging treatments. The special heterogeneous lamellar-structured alloy exhibits a high ultimate tensile strength (~1545 MPa), reasonable ductility (~7.9%), and excellent wear resistance as compared with the equiaxed grain-structured and dual-phase lamella-structured alloy. The present study demonstrates an alternative route for enhancing the tribological properties of alloys with heterogeneous lamellar structure.

  • Effect of Base Material on Microstructure and Texture Evolution of a
           Ti–6Al–4V Electron-Beam Welded Joint
    • Authors: G. Q. Wang; Z. B. Zhao; B. B. Yu; J. R. Liu; Q. J. Wang; J. H. Zhang; R. Yang; J. W. Li
      Pages: 499 - 504
      Abstract: The effect of base material (BM) on microstructure and crystallographic orientation evolution of a Ti–6Al–4V electron-beam welded joint was investigated. Meanwhile, the crystallographic orientation of prior β grains was studied by advanced electron backscattered diffraction data processing. The inhomogeneity of microstructure within welded joint was formed due to the different microstructures of BM. By comparing microstructure details of the welded joint, including microstructure morphology and crystallographic orientation with those of the base material, it can be found that both the microstructure morphology and crystallographic orientation of the EBW joint would be controlled by BM.

  • Hardware Materials in Molten Carbonate Fuel Cell: A Review
    • Authors: Ling Chen; Chao-Yi Yuh
      Pages: 289 - 295
      Abstract: The high-temperature molten carbonate fuel cell is an ultra-clean and highly efficient power generator. It is operated at ~550–650 °C, which is considered optimal in facilitating fast fuel cell reaction kinetics, utilizing waste heat efficiently, and allowing use of commercial construction materials. Commercial MW-size (mega watt) power plants of FuelCell Energy products have already been deployed worldwide. Metallic hardware materials are extensively utilized and may experience high-temperature reducing and oxidizing atmospheres in the presence of molten alkali carbonate electrolyte. Material selections are founded on many decades of focused research and development and field experience. Results to date show that the baseline stack module materials meet 5-year life goal and BOP (balance of plant) construction materials meet 20-year life goal. Material durability is well understood, and solutions are available to further extend the durability. This paper will review hardware materials experience and development approaches that would further reduce cost and extend life.

  • Corrosion Behavior and Hardness of Al– M ( M : Mo, Si, Ti, Cr)
           Alloys
    • Authors: J. Esquivel; R. K. Gupta
      Pages: 333 - 341
      Abstract: The corrosion behavior of Al–5 at.% Cr, Al–5 at.% Si, Al–5 at.% Mo and Al–5 at.% Ti produced via casting and Al–5 at.% Cr produced by high-energy ball milling and subsequent consolidation by cold pressing was studied using potentiodynamic polarization and surface analysis following constant immersion tests. Alloys were characterized using a scanning electron microscope coupled with the energy-dispersive X-ray spectroscopy and X-ray diffraction analysis. Hardness, a representative of the strength, was also measured. The alloys produced by casting contained coarse intermetallics and therefore exhibited poor corrosion resistance. Al–5 at.% Cr alloy produced by high-energy ball milling exhibited a significantly improved corrosion resistance and hardness, which was attributed to the grain refinement to nanoscale and extended solid solubility of Cr in Al.

  • Galvanic Effect Between Galvanized Steel and Carbon Fiber Reinforced
           Polymers
    • Authors: Chi Zhang; Da-Jiang Zheng; Guang-Ling Song
      Pages: 342 - 351
      Abstract: The galvanic corrosion behavior of carbon fiber reinforced polymers (CFRPs) GM-CFRP and Tepex-CFRP in contact with a Zn-coated DP590 steel in solution containing 0.9 wt% NaCl + 0.1 wt% CaCl2 + 0.075 wt% NaHCO3 was investigated. The results showed that the GM-CFRP/steel couple was initially more resistant to galvanic corrosion, but its galvanic corrosion activity gradually became higher than the Tepex-CFRP/steel couple. The different galvanic behaviors of these two couples were discussed based on the electrochemical performance of GM-CFRP, Tepex-CFRP and DP590 coupons in the testing solution.

    • Authors: Liang Fan; Fujian Tang; Signo T. Reis; Genda Chen; Michael L. Koenigstein
      Pages: 390 - 398
      Abstract: Corrosion is one of the main causes of incidents occurred in hazardous liquid and gas transmission pipelines in the USA, resulting in a loss of over $12 billion per year. In this study, the corrosion resistance of pipeline steel coated with five types of enamel was investigated in 3.5 wt% NaCl solution with linear polarization resistance and electrochemical impedance spectroscopy tests. Steel coupons were cut from API 5L X65 pipeline steel and coated with five types of enamels using the wet process. The microstructures of all enamel samples were examined by scanning electron microscopy. Experimental results indicate that all enamel coatings increase the corrosion resistance of pipeline steel, and pure enamel PE2, mixed enamels ME1 and ME2 have higher corrosion resistances than pure enamel PE1 and mixed enamel ME3.

  • Microstructure and Thermal Conductivity of Al–Graphene Composites
           Fabricated by Powder Metallurgy and Hot Rolling Techniques
    • Abstract: The objective of this research is to improve the thermal conductivity and mechanical properties of Al/GNPs (graphene nanoplatelets) nanocomposites produced by classical powder metallurgy and hot rolling techniques. The microstructural evaluation confirmed the uniform dispersion of GNPs at low content and agglomeration at higher contents of GNPs. The structure of graphene was studied before and after the mixing and the Raman spectrum proofs that the wet mixing has a great potential to be used as a dispersion method. There was no significant peak corresponding to the Al4C3 formation in both the differential scanning calorimetry curves and X-ray diffraction patterns. The microstructural observation in both fabrication techniques showed grain refinement as a function of the GNPs content. Moreover, the introduction of the GNPs not only improved the Vickers hardness of the composites but also decreased their density. The thermal conductivity investigations showed that in both the press-sintered and hot-rolled samples, although the thermal conductivity of composites was improved at low GNPs contents, it was negatively affected at high GNPs contents.

  • Influence of Silver Contents on the Tribological Properties of Ni-Based
           Self-Lubricating Coatings by Atmospheric Plasma Spraying
    • Authors: Bo Li; Jun-Hong Jia; Yi-Min Gao; Hong-Jian Guo; Min-Min Han; Wen-Zhen Wang
      Abstract: The NiCrAlY–Mo–Ag composite coatings were prepared by atmospheric plasma spraying. The tribological properties of the composite coatings were investigated from 25 to 900 °C in details. The tribo-layer formed on the worn surface of the composite coatings and influenced the tribological properties at different temperatures. The addition of silver could effectively decrease the friction coefficient and wear rate of the coatings at the wide range of temperature. The rubbing process could form the nickel molybdate and promote the formation of silver molybdate within the worn surfaces at high temperature. The synergistic lubricating effects of nickel molybdate and silver molybdate are attributed to the improvement of the tribological properties of coatings at high temperature.

  • Mechanical and Magnetic Properties of New
           (Fe,Co,Ni)–B–Si–Ta Bulk Glassy Alloys
    • Authors: Yao-Xiang Geng; Xin Lin; Yu-Xin Wang; Jian-Bing Qiang; Ying-Min Wang; Chuang Dong
      Abstract: The alloying effects of the like-atom substitution of Ni and Co for Fe on the various properties of Fe70B16.7Si8.3Ta5 metallic glass are investigated in this present work. New Fe-based bulk glassy alloys, namely Fe60–x Co x Ni10B16.7Si8.3Ta5 (at.%; x = 10, 20 and 30) with critical diameters up to 1.5 mm, were made by means of copper mold casting. A new glass-forming ability indicator, viz., the enthalpy of supercooled liquid, has been introduced for assessment of the glass-forming abilities (GFAs) of these Fe-based multi-component alloys. Nano-indentation results indicate that the calculated elastic modulus and hardness of the bulk glassy alloys are lower than those of the Fe70B16.7Si8.3Ta5 alloy. Among these bulk glassy alloys, Fe70B16.7Si8.3Ta5 exhibits the large elastic modulus and hardness with values of 178 ± 1 GPa and 12.9 ± 0.1 GPa, respectively. All the bulk glassy alloys exhibit good soft magnetic properties with high saturation magnetization B s ~ 0.75–1.04 T but low coercive force H c ~ 0.2–5.2 A/m.

  • Compressive Strength and Interface Microstructure of PCBN Grains Brazed
           with High-Frequency Induction Heating Method
    • Authors: Ye-Jun Zhu; Wen-Feng Ding; Ze-Yu Zhao; Yu-Can Fu; Hong-Hua Su
      Abstract: In order to prepare monolayer brazed superabrasive wheels, the polycrystalline cubic boron nitride (PCBN) grains were brazed to AISI 1045 steel matrix with Ag–Cu–Ti filler alloy using the high-frequency induction heating technique. The compressive strengths of brazed grains were measured. Morphology, chemical composition and phase component of the brazing resultant around PCBN grain were also characterized. The results show that the maximum compressive strength of brazed grains is obtained in the case of brazing temperature of 965 °C, which does not decrease the original grain strength. Strong joining between Ag–Cu–Ti alloy and PCBN grains is dependent on the brazing resultants, such as TiB2, TiN and AlTi3, the formation mechanism of which is also discussed. Under the given experimental conditions, the optimum heating parameters were determined to be current magnitude of 24 A and scanning speed of 0.5 mm/s. Finally, the brazing-induced residual tensile stress, which has a great influence on the grain fracture behavior in grinding, was determined through finite element analysis.

  • A Review on Grain Refinement of Aluminum Alloys: Progresses, Challenges
           and Prospects
    • Authors: Ren-Guo Guan; Di Tie
      Abstract: Aluminum becomes the most popular nonferrous metal and is widely used in many fields such as packaging, building transportation and electrical materials due to its rich resource, light weight, good mechanical properties, suitable corrosion resistance and excellent electrical conductivity. Grain refinement, which is obtained by changing the size of grain structure by different techniques, is a preferred method to improve simultaneously the strength and plasticity of metallic materials. Therefore, grain refining of aluminum is regarded as a key technique in aluminum processing industry. Up to now, there have been a number of techniques for aluminum grain refining. All the techniques can be classified as four categories as follows: grain refining by vibration and stirring during solidification, rapid solidification, the addition of grain refiner and severe plastic deformation. Each of them has its own merits and demerits as well as applicable conditions, and there are still some arguments in the understanding of the mechanisms of these techniques. In this article, the research progresses and challenges encountered in the present techniques and the future research issues and directions are summarized.

  • Corrosion Behavior of AZ31 Magnesium Alloy in Highly Alkaline Environment
    • Authors: Somi Doja; Lukas Bichler; Simon Fan
      Abstract: Industrial components made with a magnesium–aluminum alloy AZ31 are often used in diverse engineering applications where component weight, strength, and durability are critical. Similarly as other Mg alloys, however, the AZ31 is susceptible to corrosion in alkaline environments. In this work, corrosion of commercial grade AZ31 alloy plate was examined in potassium hydroxide (KOH) using immersion and potentiodynamic studies. The results suggest that the concentration of Al and Mn in the alloy may govern the kinetics of micro-galvanic corrosion and the initiation of corrosion pits. Further, trace amounts of Ni in the AZ31 alloy were seen to enable formation of Ni(OH)2 surface layer, which may have further accelerated alloy corrosion due to its cracking and void coalescence. The effect of pH on the corrosion behavior of AZ31 was studied with reference to Pourbaix diagrams.

  • Long-term Field Corrosion Monitoring in Supporting Structures of China
           Xiamen Xiangan Subsea Tunnel
    • Authors: Chao-Yang Gong; Xiao-Yong He; Yong-Wei Li; Si-Zhe He; Xuan Cheng; Liu-Ying Huang; Ying Zhang; Jiu-Bin Chen; Shao-Hui Xu; Jian-Bin Zhang; Chao Zeng
      Abstract: Xiamen Xiangan Subsea Tunnel is the first undersea tunnel constructed in China. It has become the major undersea pathway connecting Xiamen Island and Xiangan District since its operation in 2010. The total length is 6.05 km with the undersea length of 4.2 km. In an effort to onsite-monitor reinforcement corrosion in concrete structures, the commercially available CorroWatch multiprobe sensors and ERE-20 reference electrodes were pre-embedded in the selected locations and positions of supporting structures during the tunnel constructions. The real-time data have been collected annually by onsite measurements for 6 years. In this paper, the feasibility of the onsite corrosion monitoring system and suitability of the measured parameters including corrosion current, potential and temperature are discussed based on the preliminary results. The measured typical cyclic-type variations in corrosion current and temperature with monitoring time might be related to the seasonal changes during the annual routine measurements. The widely scattered corrosion potentials that are fluctuated complicatedly reflected localized differences in the vicinity of rebar and concrete. These findings, along with the progressively ongoing research, will provide valuable information in structural durability for service life prediction of reinforced concrete structures exposed to marine environments.
