在实用金属中,镁合金的密度最小,而且镁合金具有优异的比强度、屈强比、切削性、再生性。近年来,在便携式电子产品以及家电产品的壳体应用方面正在扩大。镁合金具有密排六方晶体结构,属难加工的材料,可是当进行温加工或热加工时,较易形成微细晶粒组织,有望使底面滑移以外的滑移系发生作用,而提高其成形性。 Among practical metals, magnesium alloys have the lowest density and magnesium alloys have excellent specific strength, yield strength, machinability and recyclability. In recent years, housing applications for portable electronics and home appliances have been expanding. Magnesium alloy with close-packed hexagonal crystal structure, is difficult to process the material, but when the temperature processing or thermal processing, the more likely to form fine grain structure, is expected to make the sliding slip other than the bottom surface of the system to play an active role in improving the formation Sex.
