Bibliography: | 为了提高ZK60镁合金的力学性能,采用多向锻造和部分重熔工艺;研究重熔温度和保温时间对ZK60镁合金半固态组织的影响;研究多向锻造和部分重熔工艺制备的ZK60镁合金构件在不同触变成形温度下的力学性能。结果表明:多向锻造加部分重熔工艺是一种制备半固态触变成形ZK60镁合金的有效方法。在部分重熔过程中,随着保温时间的延长和重熔温度的升高,晶粒长大。升高重熔温度,晶粒球化效果明显得到改善。当触变成形温度从560°C升高至574°C时,ZK60镁合金的力学性能明显提高 43-1239/TG ZK60 Mg alloy;semi-solid processing;multi-axial forging;mechanical properties;microstructure TAO Jian-quan1, CHENG Yuan-sheng2, HUANG Shao-dong1, PENG Fei-fei1, YANG Wen-xuan1, LU Mei-qi1, ZHANG Zhi-ming1, JIN Xin1 1.
