摘　　要：研究了2091铝锂合金焊后热处理对焊接接头机械性能的影响。结果表明。对2091铝锂合金进行焊后热处理,可以显著提高其接头强度,对塑性的影响不明显。Effects of post-weld heat treatment on the mechanical properties of Al-Li alloy 2091 joints are studied in this paper. The result shows that post-weld heat treatment can raise the strength of the joint enomously, but have weak effect on the elongation.
