中文摘要	the mg-8gd-2y-1nd-0.3zn-0.6zr (wt.%) alloy sheet was prepared by hot extrusion technique, and the structure and mechanical properties of the extruded alloy were investigated. the results show that the alloy in different states is mainly composed of alpha-mg solid solution and secondary phases of mg5re and mg24re5 (re = gd, y and nd). at aging temperatures from 200 degrees c to 300 degrees c the alloy exhibits obvious age-hardening response. great improvement of mechanical properties is observed in the peak-aged state alloy (aged at 200 degrees c for 60 h), the ultimate tensile strength (sigma(b)), tensile yield strength (sigma(0.2)) and elongation (epsilon) are 376 mpa, 270 mpa and 14.2% at room temperature (rt), and 206 mpa. 153 mpa and 25.4% at 300 degrees c, respectively, the alloy exhibits high thermal stability.
