摘　　要：本文分析了3J1合金在热剪切时发生开裂的原因,结果表明,合金锻坯心部存在Ti元素偏析;导致富Ti区热塑性下降,剪切时,富Ti区一旦暴露就产生开裂。This paper analyzas the cause of hot shear cracking in alloy 3J1. The results show that Ti Segregation in the core of forged alloy blank leads to the increase of hot plasticity in the Ti-rich zone and the Revelation of the Ti-rich zone during shearing results in cracking.

关 键 词：锻造 弹性合金 热剪切 开裂 钛 偏析
