摘要：

The effects of combined addition of Zn and Ca to Mg-1Gd alloy (Mg-1Gd-1.5Zn-1Ca wt.%) on its microstructure and mechanical properties were studied. The results showed that the fine and coarse Mg2Ca and Ca2Mg6Zn3 phase particles were formed in the matrix by the combined additions of Zn and Ca. A drastic refinement of dynamic recrystallized grains was observed in the extruded Mg-1Gd-1.5Zn-1Ca alloy sheet. A remarkable yield strength enhancement and minor ductility decrement have been observed, where strength remarkably increases from 73 to 153 MPa along ED and from 119 to 182 MPa along TD and th...
