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。
At 420 ℃, the LC4 of the super-hard aluminum alloy was compressed at different times. Combined with the observation of metallographic microstructure and the mechanical property test, the deformation of the T6 microstructure at the same deformation temperature and the same deformation was studied. And the impact of performance. The results show that with the increase of heat deformation times, the hardness value of LC4 aluminum alloy after solution treatment is significantly increased.
