A primary study on tensile strength stability of Mg-5Y-3Sm-0.5Sb alloy
The tensile strength stability of aging hardened Mg-5Y-3Sm-0.5Sb alloy was primarily studied.The results showed that the alloy has good tensile strength at room and high temperature.The tensile strength decreases slowly from 258 MPa at room temperature to 195 MPa at 300 ℃.The tensile strength stability is superior to that of commercial heat resistant magnesium alloy WE54 developed most successfully.The formation of Mg24Y5 phase is observed in the alloy.The tensile strength of the alloy keeps a linear relationship with the hardness of strengthening phase Mg24Y5.The reason for the tensile strength stability is mainly attributed to the hardness stability of Mg24Y5 phase in the alloy.
