摘　　要：对变形镁合金Mg-3.5Y-0.8Ca-0.5Zr进行热轧实验,并对轧制板带的显微组织形貌和力学性能进行了分析。结果表明,通过热轧可获得厚度为0.5 mm的Mg-3.5Y-0.8Ca-0.5Zr轧制板带,板带晶粒尺寸小于铸态组织的晶粒尺寸。随着轧制道次的增加,板带抗拉强度呈现先增大后减小的变化趋势,伸长率随轧制道次的增加呈现增大的趋势。Hot-rolling experiment of Mg-3.5Y-0.8Ca-0.5Zr Wrought magnesium alloy was carried out.The microstructure and the mechanical properties of Mg-3.5Y-0.8Ca-0.5Zr alloy plates were studied.The results indicated that the grains size of Mg-Y-Ca-Zr rolling plates was less than that of as-cast alloy.With an increase of rolling pass,the elongation percentage raised while the tensile strength of Mg-Y-Ca-Zr alloy exhibited a trend of first increase and then decrease.
