摘要：
The microstructure and mechanical properties of Mg-5Y-3Sm-0.8Ca-0.5Sb alloy were investigated by micro-structure analysis and tensile tests. The results showed that the microstructure of as-cast Mg-5Y-3Sm-0.8Ca-0.5Sb alloy consists of α-Mg matrix and Mg24Y5, Mg41Sm5, Mg2Ca and Mg3Sb2. The aged Mg-5Y-3Sm-0.8Ca-0.5Sb alloy has good mechanical properties at room and high temperature. Its ultimate tensile strength is 266 MPa, 244 MPa and 208 MPa at room temperature, 200℃ and 300℃ respectively. The stability of its ultimate tensile strength is superior to that of heat resistant magnesium alloy WE43 developed most successfully. ©, 5015, Editorial Office of Chinese Rare Earths.
