Abstract :
The microstructure and mechanical properties of aged Mg-10Y-2.5Sm alloy were investigated. The results showed that the microstructure of the alloy consisted of α-Mg matrix and Mg24Y5 phase, and fine Mg24Y5 particles distributed in a-Mg matrix uniformly and dispersedly. Sm enhanced α-Mg matrix and Mg24Y5 phase by solid solution effect. At 200-300 °C, the ultimate tensile strengths were more than 200 MPa and the elongations were about 3%. Compared with those at room temperature, the mechanical properties had no obvious changes.
