摘　　要：由于 AZ 系变形镁合金属于密排六方结构,其塑性变形性能和机械性能相对较差。采用晶粒细化的方法可大大改善镁合金的力学性能。本文通过对自制的新型晶粒细化剂(Al-Ti-C-RE)与常规的细化剂(MgCO_3)的细化作用的比较发现,新开发的晶粒细化剂 Al-Ti-C-RE 可以更有效地细化镁合金的晶粒,提高 AZ系镁合金的综合力学性能。The mechanical property and plasticity of AZ series magnesium alloys are some lower comparatively because of its close- packed hexagonal structure.But,the mechanical properties can be greatly improved by grain refining.In this paper,the effectiveness of newly developed grain refiner(Al-Ti-C-RE)by the author is compared with traditional grain refiner(MgCO_3),the results show that the Al-Ti-C-RE can refine the AZ series magnesium alloys and improve their overall properties more effectively.
