摘要
A series high temperature creep resistance magnesium alloy for die casting based on AZ91 was successful developed by addition of Rare Earth, and Calcium. The original target of magnesium alloy development was aimed at cylinder head cover of high power diesel engine, and tried to satisfy the temperature demands of gear-box house. The tensile property at room temperature, creep behavior at 150 ℃ , and analysis of microstructure was discussed in this paper. The results show that the series high temperature creep resistance magnesium alloy for die casting has potential to produce power-train parts, and greatly decrease the weigh of parts.
