用热模拟压缩方法测得Ｔｉ－１７合金在温度为８０５～９４５℃、应变速率ε为１０－３～８０ｓ－１、变形程度。在５０％范围内的真应力─应变曲线，研究了不同温度、不同应变速率下的流动应力及组织变化规律。发现：β区变形是以扩散国复型变形机制占主导地位，在高温、低应变速率下易发生连续再结晶；在（α＋β）两相区变形以位错滑移机制为主，低温、高应变速率时发生动态再结晶；近β区是两种机制的综合作用。试验还应用Ｘｉｎｅｒ－Ｈｏｌｌｏｍｏｎ因子确定了发生连续再结晶的临界因子ｌｏｇＺｃ＝４１．２，从而表明连续再结晶与高温回复形成亚结构有关。
Ti-17 alloy was measured by thermal simulation compression method at a temperature of 805 ~ 945 ℃ and a strain rate ε of 10-3 ~ 80s-1. The true stress-strain curve in the range of 50%, the flow stress and microstructure change under different temperatures and different strain rates were studied. It is found that the deformation of β zone is dominated by the complex deformation mechanism of diffusional state and continuous recrystallization is easy to occur at high temperature and low strain rate. The dislocation slip mechanism is the main deformation in the (α + β) Dynamic recrystallization occurs at strain rates; the near-β region is the combined effect of the two mechanisms. The Xiner-Hollomon factor was also used to determine the critical factor for continuous recrystallization, logZc = 41.2, indicating that continuous recrystallization is associated with the formation of substructures at high temperature.
