摘　　要：利用Gleeble-3800热/力模拟试验机,进行了TA15钛合金的热压缩实验,获得了流变曲线,并基于动态材料模型建立了热加工图。结果表明:变形温度和应变速率对流动应力影响很大,在双相区变形,合金的动态软化效果明显;在单相区变形,合金的动态软化效应减弱。By applying Oleeble-3800 thermal simulation test machine, thermal compress test of TA15 titanium alloy has been canied out to obtain flow curve, further hot processing map has been established based on dynamic material model. The results showed that flow stress was influenced greatly by deformation temperature and strain rate, dynamic softening effect of alloy was evident when deformation happened at dual phase region, while the effect of alloy was weakened when deformation happened at single phase.
