摘要：
New Mg-Zn-Al-Ca based alloys are evaluated for possible application at elevated temperatures. The as-cast microstructures of these alloys show that the amount of eutectic compounds increases with an increase in Zn+Al content, and the compounds are found to be mainly Mg32(Al,Zn)49 or MgZn. High temperature tensile strength and 0.2% proof strength increase with an increase in the amount of compounds. The creep properties of the alloys are far superior to those of conventional die-cast AZ91D alloy. However, the presence of soft Mg17Al12 compound deteriorates the creep properties of high Al containing alloys.
