  • SIMULATED HEAT AFFECTED ZONE IN WELDED STAINLESS STEEL 304L

    • Authors: Soumia Hamza, Zakaria Boumerzoug, Elhadj Boumerzoug, Fabienne
      Pages: 142 - 149
      Abstract: This work is a contribution study of the heat-affected zone in the real welded joint of stainless steel 304L. This zone was compared to the heat-affected zone obtained by using a thermal cycle simulation of welding. This experimental technique is based on thermal cycle simulation of welding by rapid heating and cooling treatments of the base metal in a specific simulation equipment. The samples were analyzed by scanning electron microscopy equipped with energy dispersive X-ray, and microhardness measurements. Microstructures and mechanical properties of the simulated heat affected zone were also determined. Thermal cycle simulation technique has revealed more details on the microstructure and the mechanical behavior of the heat-affected zone.

  • EFFECT OF SPRINGBACK IN DP980 ADVANCED HIGH STRENGTH STEEL ON PRODUCT
           PRECISION IN BENDING PROCESS

    • Authors: Hung Thai Le, Kien Trung Le, Dinh Thi Vu, Phuong Thi Doan
      Pages: 150 - 157
      Abstract: Springback is a common phenomenon in sheet metal forming, in which the material undergoes an elastic recovery as applied loads are removed. Springback causes the forming shape to deviate from the intended design geometry. This phenomenon, which can be influenced by several factors, effects on both bending angle and bending curvature. The aim of this study is to determine the influence of different tool radius and the gap between punch and die on springback in bending of DP980 Advanced High-Strength Steels (AHSS) sheet. Experimental studies are combined with FEM method in commercial ABAQUS software to determine the bending angle after springback. To predict springback in bending process, the material properties are defined by Ludwik - Hollomon law, combined with the Hill’48 criterion. Experimental results are in good agreement with numerical simulations in case of bending in the rolling direction.

  • INFLUENCE OF RARE-EARTH ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF
           HIGH MANGANESE STEEL UNDER IMPACT LOAD

    • Authors: Duong Nam Nguyen, Duong Nguyen Nguyen, Mai Khanh Pham
      Pages: 158 - 165
      Abstract: In this paper, the influence of rare earth (RE) on the microstructure and mechanical properties of austenitic high manganese steel (HMnS) Mn15Cr2V were investigated. The results showed that the microstructure, hardness and impact strength of RE modification sample is finer and better than non-modified sample. Under the effect of impact load, the hardness and the depth of the work-hardening layer of the modified steel was higher than that of the non-modified steel, thereby, the value of microhardness in the surface of the modified sample was 420 HV while it was only 395 HV in the non-modified sample. The value of the impact strength of the modified sample was up to 132 J/cm2 compared to the non-modified sample is only 115 J/cm2. Moreover, after impact load, the austenite nanoparticles had been found out on the surface of this steel, this is the cause of the increasing of mechanical properties in this steel.

  • INDENTATION SIZE EFFECT OF HEAT TREATED ALUMINUM ALLOY

    • Authors: Jozef Petrík, Peter Blaško, Andrea Vasilňaková, Peter Demeter, Peter Futaš
      Pages: 166 - 173
      Abstract: The aim of the submitted work is to study the influence of applied  loads ranging from 0.09807 N to 0.9807 N on measured values of micro-hardness of heat treated aluminum alloy 6082. The influence of applied load on a measured value of micro-hardness was evaluated by Meyer’s index n, PSR method and by Analysis of Variance (ANOVA).  The influence of the load on the measured value of micro-hardness is statistically significant and the relationship between the applied load and micro-hardness manifests the moderate reverse ISE. As the temperature of the solution treatment rises, the YS/UTS ratio and also Meyer’s index n, measured and “true hardness“  increase. On the other hand, its effect on the plastic properties of the alloy is ambiguous.

           APPLICATION

    • Authors: Bui Duc Long, Duong Ngoc Binh, Le Hong Thang, Le Thi Bang, Suhana Binti Mohd Said
      Pages: 174 - 179
      Abstract: Quaternary chalcogenide Cu2ZnSnS4 is a potential candidate for thermoelectric (TE) application due to a number of advantages including containing only non-toxic and abundant elements, high Seebeck coefficient and low thermal conductivity. In this study, Cu2ZnSnS4 was synthesized using mechanical alloying method from Cu, Zn, Sn and S powders. In order to study the effect of milling duration on the formation of Cu2ZnSnS4, different milling duration of 2, 4, 12 and 16 h were investigated. As the results, Cu2ZnSnS4 was started to form after milling for 12 h. The formation of Cu2ZnSnS4 was completed after 16 h of milling. In addition, Cu2ZnSnS4 nanoparticles were obtained after 16 h of milling with the distribution mostly in the range of 50 - 60 nm.

  • STUDY OF M23C6 PRECIPITATION IN A 45Ni-35Cr-Nb ALLOY

    • Authors: Matías Humberto Sosa Lissarrague, Alejandro Sepulveda Buitrago, Alberto Carlos Picasso
      Pages: 180 - 185
      Abstract: The 45Ni-35Cr-Nb alloy, commonly known as ET45 micro, produced in the form of centrifugally cast tubes, was studied by means of optical microscopy after aging treatments at 1073 and 1173 K for different times. A description of M23C6 secondary carbides precipitation phenomenon was made as a function of time. The analysis after using the Johnson–Mehl–Avrami–Kolmogorov (JMAK) model showed that the secondary carbide precipitation occurs in a single stage. It was found that this phenomenon, which is assisted by diffusion, has an activation energy of 196 kJ/mol.

  • FABRICATION OF TRANSPARENT MgAl2O4 SPINEL CERAMICS BY PECS PROCESSING OF
           COMBUSTION - SYTHESIZED NANOPOWDERS

    • Authors: Yen Ngoc Nguyen, Anh-Tu Dao, Minh-Hai Le, Khanh Quoc Dang, Makoto Nanko
      Pages: 186 - 192
      Abstract: Transparent MgAl2O4 ceramic could be found in a wide range of applications for both military and civil sector due to its high melting point, good mechanical properties, small refractive index (1.71) and its ability to allow light in range from UV to mid-IR to pass through. In the present work, transparent MgAl2O4 were fabricated from metal nitrates via two steps. Firstly, the MgAl2O4 nanopowder was synthesized via solution combustion synthesis from the metal nitrates. Secondly, the powder was then consolidated by Pulsed Electric Current Sintering (PECS) technique to fabricate transparent ceramic. XRD patterns of the obtained powder showed the peaks of only MgAl2O4 phase. Besides, the atomic compositions of magnesium, aluminium and oxygen determined by EDX analysis were approximately corresponded to 1:2:4 of the molecular formula of MgAl2O4. After deagglomerating for 48 hours using soft ball-milling, the powder had the average particle of 27 nm. Transparent MgAl2O4 samples, which were sintered with two-step sintering mode of 1050oC/60 minutes-1400oC/20 minutes, permitted the transmission of visible and infrared light with the transmittance up to 80%, Vickers hardness of 14.2 GPa, and fracture toughness of 1.1 MPa.m1/2. The results are a critical step toward fabrication of high-quality transparent ceramics from metal nitrates.

  • EFFECT OF GATING SHAPE AND DIRECTION DURING CENTRIFUGAL CASTING OF
           ARTIFICIAL LUMBAR DISC MODEL OF CP-TI

    • Authors: Lilik Setyana, Muslim Mahardika, Sutiyoko Sutiyoko, Suyitno Suyitno
      Pages: 193 - 202
      Abstract: Shape and direction of gating in centrifugal casting affected the microstructures and defects. The purpose of this research was to determine the effects of gating shape and direction in centrifugal casting toward porosity, density, roughness, and microstructures on the artificial lumbar disc model. The main shapes of gating were circular and rectangular cross-section.  The circular cross-section gating was used for two different directions of artificial lumbar discs; vertical, and horizontal. Furthermore, the rectangular cross-section design consisted of three different directions; oblique clockwise, oblique counter-clockwise and perpendicular towards the mold. The rotational mold was conducted at a speed of 60 rpm. The results showed that the rectangular cross-section gating with the oblique direction same with the rotation of the mold produced artificial lumbar disc model that had the smallest porosity area among the other directions. It was the best gating design among the others which had the smallest porosity area (0,68%), highest density (4,517 g/cm3), and smoothest roughness (8,76 µm). In the sub-surface, the microstructure of α-case was formed. The thickness and hardness of the α-case in this design were 50-100 µm and 760 VHN, respectively. Hence, the rectangular cross-section gating with the oblique direction same with the rotation of the mold was appropriate to be applied in the manufacture of an artificial lumbar disc model.
