“…This activation of pyramidal slip system is believed to produce extensive plasticity. Hence, the ductility seems to increase in Mg-10%Y as compared to Mg-5%Y in reference [20]. The increase in strength from 5 wt%-10 wt% (Table 2), in this study, is reported to be due to the precipitation of β' phase from supersaturated solid solution [20].…”

Magnesium-rare earth based alloys are increasingly being investigated due to the formation of highly stable strengthening phases, activation of additional deformation modes and improvement in mechanical properties. Several investigations have been done to study the effect of rare earths when they are alloyed to pure magnesium and other Mg alloys. In this review, the mechanical properties of the previously investigated different magnesium-rare earth based binary alloys, ternary alloys and other higher alloys with more than three alloying elements are presented.

“…3,4) A Mg-10Y-2Zn (all of the percentages refer to weight percentage if not specified otherwise) alloy also processed by rapidly solidified powder metallurgy exhibits a tensile strength of 520 MPa. 5) As-cast Mg-Zn-Y alloys have yield stresses from 180 to 480 MPa, depending on their composition. 6) Thus, the Mg-Zn-Y system is an ideal candidate for developing high-performance magnesium alloys, and investigation of this system is one of the hottest topics in the development of new magnesium alloys.…”

The effects of reheating temperature and time on the microstructure and mechanical properties of thixoforged ZW21 alloy were investigated. The results indicate that the ZW21 alloy is suitable for thixoforming in view of its thixoformability and the resulting mechanical properties. The reheating temperature and duration mainly affect the microstructure, including the size and fraction of primary particles, the microstructure compactness, the solubilities of the solute elements and W phase content, and thus the mechanical properties of the thixoforged alloy. The effects of the reheating temperature are larger than that of the reheating time. These two parameters have an optimum critical value, and values less than or higher than this value decrease the mechanical properties. The appropriate reheating technique is heating for 70 min at 913 K, and the resulting ultimate tensile strength, elongation, and hardness can be up to 238 MPa, 19.4%, and 58 HV, respectively. As the reheating temperature or reheating time increases, the fracture regime has a tendency to change from intergranular mode to transgranular mode and finally to intergranular mode again.
