to develop some new magnesium alloys with good creep properties, acceptable castability and low cost. Recent investigations reveal that alloys based on Mg-Zn-Al ternary system are promising to meet the above requirements[4]. So far, most of the researches concerning Mg-Zn-Al based alloys focused on the alloys with high Zn (＞8%, mass fraction) and Al (＞5%, mass fraction) concentrations[5......
