“…It is a candidate lightweight material for use in aerospace and automobile applications at high temperatures. 3,4) At the present, commercial products of WE43 alloy are always produced by casting due to its low deformability. Some research on creep and cracking in WE43 alloy and on structural aspects of that alloy has focused on the cast material and not on deformed alloy plate.…”

The influence of T5 and T6 tempers at 523 K on the mechanical properties and microstructure of hot-rolled WE43 alloy has been studied. The microstructure of the alloy under various conditions was studied using an optical microscope, a transmission electron microscope, and a xray diffractometer. The mechanical properties were measured on a tensile testing system. The results show that the hot-rolled WE43 alloy has a substantially higher hardness and strength improvement than the cast WE43 alloy. The hot-rolled WE43 alloy with a T5 temper showed better properties than the alloy with a T6 temper because both strain hardening and age hardening increased the strength of the alloy. In addition, the size of the precipitates after a T5 temper was smaller than that after a T6 temper. The yield strength of the alloy parallel to the rolling direction was higher than that perpendicular to the rolling direction.

“…[2][3][4] Although the strengthening mechanism of Mg-Y-Zn alloys is less well understood, it is considered to be mainly due to solution hardening of Y in the Mg solid solution ( phase) and precipitation hardening by the intermediate phase (X phase). 5) It is certain that the X phase has distinctive long-period stacking ordered (LPSO) structures, which vary with the alloy composition or heat treatment, 6) and it is considered to have a significant effect on the mechanical properties of this alloy. As a matter of course, the establishment of a phase diagram is important for efficient alloy development and optimization of manufacturing processes.…”

Liquid-Solid Equilibrium and Intermediate Phase Formation during Solidification in Mg-1.3 at%Zn-1.7 at%Y Alloy

et al. 2008

Mg-Y-Zn alloys have attracted much attention in recent years due to their excellent mechanical properties, which are said to be the effect of the intermediate phase (X phase) in the Mg solid solution ( phase). The formation behavior of the X phase has been reported to be a eutectic type reaction in the Mg-Y-Zn pseudo-binary system. However, the phase diagram of this system still requires clarification. In the present study, the 97.0Mg-1.3Zn-1.7Y (at%) alloy was prepared to clarify the liquidus and solidus in the liquid-solid coexistence region, and the solubility limit in the phase. The chemical compositions of the alloy were analyzed by electron probe X-ray microanalysis after isothermal heat treatment. The results indicate that the Mg-Y-Zn ternary system can be represented as a pseudo-binary system between the and X phases. In addition, the solidus line for the phase has been clarified. The solubility limit for the phase is not much different from that of the previous report, whereas the formation behavior of the X phase is not in the manner of a eutectic reaction, but rather that of a peritectic one.

“…Thus, Mg alloys have been widely used in thixomolding and casting products [7,8]. To increase the utility of these alloys, attempts to increase their strength and formability have been made [9][10][11][12]. Mg alloys have been used in vehicles, and they have recently been used as secondary strength members in cell phones, electronic devices, and so forth [13,14].…”

Magnesium alloys can be used for reducing the weight of various structural products, because of their high specific strength. They have attracted considerable attention as materials with a reduced environmental load, since they help to save both resources and energy. In order to use Mg alloys for manufacturing vehicles, it is important to investigate the deformation mechanism and transition point for optimizing the material and vehicle design. In this study, we investigated the transition of the deformation mechanism during the high-temperature uniaxial tensile deformation of the AZ31 Mg alloy. At a test temperature of 523 K and an initial strain rate of 3 × 10 −3 s −1 , the AZ31 Mg alloy (mean grain size: ∼5 μm) exhibited stable deformation behavior and the deformation mechanism changed to one dominated by grain boundary sliding.
