中文摘要：
在变形温度1030~1120℃,应变速率0.001~1.0 s-1,最大变形程度50%时对TC11钛合金进行了高温压缩热模拟试验。分析了TC11钛合金高温流变应力—应变曲线变化规律;分析了变形温度、应变速率和变形程度对组织性能的影响规律。结果表明：在应变速率较小时,TC11钛合金的α相被拉断,在原始晶界处出现细小的晶粒;在应变速率较高时,α相晶粒呈细小的等轴晶;变形温度越低,初生α相的含量越多。
英文摘要：
Hot compression simulation experiment of TC11 titanium alloy was performed at deformation temperature of 1030-1120℃, strain-rate of 0.001-1.0 s-1 and deformation degree of 50%. The law of stress-strain curve of TC11 titanium alloy was analyzed. The influences of deformation temperature, strain-rate and deformation degree on microstructure and properties were also analyzed. The results show that： when strain rate is smaller, α phase of TC11 titanium alloy is broken, and fine grains are produced in original grain boundary. When strain rate is higher, α phase is fine equiaxed crystal. The lower the deformation temperature is, the more the content of primary α phase is.
