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。改变模拟特性参数、应变速率对合金的热塑性行为有较大的影响。
The thermomechanical properties of Al-Li alloy were studied by using welding thermal simulation technology to simulate the thermal cycling temperature effect of welding. Changing the simulation parameters, the strain rate has a great influence on the thermoplastic behavior of the alloy.
