摘　　要：Ti-80是一种近α型钛合金,应用非常广泛,检测一组Ti-80冲击试样时,发现冲击韧性存在差别,分析了出现差别的原因.根据分析,初生α相含量以及形状不同,是导致冲击韧性出现差别的主要原因,而导致初生α相含量以及形状不同的可能原因则是Ti-80钛合金在热处理时温度不均.Ti -80 is a type of near alpha titanium alloy. Its application is extensive. In our testing of a group of impact specimen of Ti - 80, there was a difference in the impact tough- ness. According to our analysis, the difference in impact toughness is found to be in primary α phase＇ s differing contents and shapes, which may result from the uneven temperature during the thermal treatment of Ti -80.
