摘　　要：研究了ZL201A铝合金热处理后组织演变和冲击性能。结果表明,热处理后原始粗大的网状共晶组织消失,元素偏析情况得到改善。热处理使合金的综合性能得到了改善,试样的冲击功显著增加,抗冲击性能得到提高,合金更有利于在恶劣环境服役。The microstructure evolution and impact properties of ZL201A aluminum alloy after heat treatment were studied. The results show that the original coarse network eutectic structure disappeared aider heat treatment and the element segregation was improved. The comprehensive properties of the alloy are improved with heat treatment. The impact energy of the samples increases significantly, and the impact resistance was improved. Alloys are more conducive to service in severe environments.
