摘　　要：在420℃对超硬铝合金LC4进行不同次数的压缩,并结合金相显微组织观察、力学性能测试等方法,研究试样在相同变形温度、相同变形量下,变形次数对其T6态显微组织和性能的影响。结果表明:随着热变形次数的增加,LC4铝合金经固溶处理、时效处理后的硬度值显著增加。LC4 alloy was deformed with different times at 420 ℃. The influences of deforming times on microstructure and property of the alloy which have the same deformation temperature and the same deformation were studied by the microstructure observation methods and mechanical properties test. The results show that with the increase of heat deforming times, the hardness of LC4 alloy increases significantly after the same solid solution and aging treatment.
