description In the Mg–Zn system it has been shown that the addition of trace amounts of Ca can have a substantial positive influence on the precipitation process during artificial ageing. The microstructure of the modified alloy is more complex and has a much refined precipitate structure that is very stable for prolonged periods at elevated temperatures (⩽450 K), leading to a significant improvement in creep resistance.
