The as-cast microstructure of Mg-5Al-3Ca-xY alloy consists of dendritic  -Mg matrix, (Mg, Al)2Ca eutectic phase and Al2Y intermetallic compounds. These two kind of (Mg, Al)2Ca compounds were observed: coarse irregular-shape structure at grain boundary and fine needle-shape structure in the  -Mg matrix grain. This (Mg, Al)2Ca phase of the extruded alloys was elongated to extrusion direction and size of this phase was refined comparing with that of as-cast alloys because of severe deformation during hot extrusion. Maximum yield and ultimate strength value of extruded alloys was 326 and 331 MPa at Mg-5Al-3Ca-3Y alloy, respectively. From these results, it is conclusively demonstrated that Y additions on Mg-5Al-3Ca alloy have more effect to improve mechanical properties. [doi:10.2320/matertrans.MC200777]
