Precipitation-hardened Mg-Ca-Zn alloys with superior creep resistance

The present paper reports the development of creep resistant Mg-Ca-Zn based alloys that can be strengthened via age hardening. The Mg-1Ca-1Zn-0.6Zr (wt.%) alloy shows tensile and creep properties superior to magnesium alloy AZ91. The addition of 1 wt.% Nd to this alloy leads to further improvements in yield strength and creep resistance.
