Popis:	As-cast Mg-2Zn-1Mn-xCa (x=0.5 and 1.5 wt.%) alloys are extruded a 553K with an extrusion ratio of 11.3:1 as biomedical materials. The microstructures of the extruded Mg-2Zn-1Mn-xCa alloys are investigated. Microstructures show that the dynamic recrystallization (DRX) occurs after the extruded process. The grain size of the extruded Mg-2Zn-1Mn-1.5Ca alloy is significantly refined compared to that of Mg-2Zn-1Mn-0.5Ca alloy. The tensile strength increases and the elongation decreases with an increase of Ca content. The improvement of tensile strength can be attibuted to the pesence of Mg2Ca phase. However, Mg2Ca phase is bristle, which results in the elongation reducing.
