摘　　要：本文采用焊接热模拟技术，模拟焊接热循环温度效应，研究了Ａｌ－Ｌｉ合金的热塑性特性和焊接热裂纹敏感性，发现Ａｌ－Ｌｉ合金具有与ＬＧ＿２铝相同或更良好的可焊性能。The temperature effect of welding heat cycling was simulated using weldingheat simulation technique to investigate the thermoplastic characteristics of aluminum-lithi-um allovs and their thermal crack sensitivities to welding。The results showed that alu-minum-lithium allovs are comparable to or even more excellent than LG2 aluminurn in weld-ability。
