, such as AZ91 and AM60 based on Mg-Al system, limit the application of these alloys to temperatures below 120 ℃[1]. Some magnesium alloys containing rare earth developed in past decades exhibit high... 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......
