摘　　要：研究了轧制工艺对镁合金微观组织和力学性能的影响。结果表明,随着轧制道次的增加,镁合金组织中孪晶组织越来越多。随着轧制温度的提高,镁合金变形能力增加,但晶粒长大,且氧化程度加剧。镁合金抗拉强度、屈服强度和伸长率随轧制道次增加而升高。随轧制温度增加,镁合金抗拉强度和屈服强度降低,伸长率升高。The effect of rolling technology on the microstructure and mechnical properties of Mg alloy was studied. The results show that with the increase of rolling passes, more and more twins appear in microstructure of magnesium alloy. With the increase of rolling temperature, the deformation capacity of Mg alloy increases, but the grain size increases, and the degree of oxidation increases. The tensile strength, yield strength and elongation of the magnesium alloy increase with the increase of the rolling passes. The tensile strength and yield strength of magnesium alloy decrease and the elongation increases with the increase of rolling temperature.
