| 摘 要： | 通过高温和室温拉伸试验，研究了变形温度和变形程度对Ｔｉ－３１合金板材性能和组织的影响。结果表明，合金在７５０～８５０℃的温度下变形５％～２０％空冷后，其室温机械性能均能达到材料的技术指标要求。并发现了材料在９００℃的临界变形区。

| Abstract: | Through tensile tests on Ti-31 alloy plates at room temperature and high temperature respectively the effects of hot forming on their properties and microstructure are studied.The results show that after the alloy subjected to 5%～20% deformation and air cooling, its mechanical properties can meet the technical requirement for the alloy and a critical deformation zone at 900℃ was found. |
