In recent years

magnesium alloys have attracted much attention because of their lower density

higher specific strength and higher specific stiffness. However

due to the low plasticity and toughness of magnesium alloy and the poor formability at room temperature

the application of magnesium alloy was limited. The formability and ductility of magnesium alloys can be improved by adding some elements

such as zinc and calcium. Mg-Zn-Ca alloys have attracted more and more attention due to their low cost

good precipitation hardening properties

creep resistance and good biodegradability. The research progress in Mg-Zn-Ca alloys in recent years was summarized focusing on material research

alloying and processing methods of Mg-Zn-Ca alloys at home and abroad

and the future development of Mg-Zn-Ca alloys was prospected.
