Effects of Solid Solution Treatments on Microstructures and Tensile Properties of a Mg-Y-Zn-Cu Alloy
In this study,a Mg-2.1Y-0.5Zn-0.6Cu-0.1Zr (WZC200,in at.%) alloy was prepared by permanent casting method.On the basis of thermal analysis results during solidification process,two temperatures (T1/763K and T2/773K) were selected for subsequent solid solution treatments.Microstructure evolution and the tensile property changes after T4 treatment at T1 and T2 for different holding time were also investigated in this study.The tensile testing results showed that yield strength and ultimate tensile strength were improved with the fraction increase of the lamellae-shaped LPSO phase in the grain interiors,rather than the total fraction of LPSO phase.
