采用Gleeble−1500热模拟试验机对TB10合金进行高温压缩变形实验，分析该合金在变形温度为700~1 050 ℃，应变速率为0.1~50 s−1条件下的变形行为及流变应力的变化规律。
Ti5Mo5V2Cr3Al合金热变形行为Hot deformation behavior of Ti5Mo5V2Cr3Al alloy采用Gleeble−1500热模拟试验机对TB10合金进行高温压缩变形实验，分析该合金在变形温度为700~1 050 ℃，应变速率为0.1~50 s−1条件下的变形行为及流变应力的变化规律。结果表明，流变应力受变形温度和应变速率显著影响，流变应力随变形温度的升高和应变速率的降低而降低。采用双曲正弦模型确定该合金的变形激活能Q和应力指数n，建立了相应的热变形本构关系。
The hot compression deformation behavior of TB10 alloy was investigated by Gleeble−1500 simulator at the strain rate range from 0.1 to 50 s−1 and the temperature range from 700 to 1 050 ℃. The laws of microstructure evolvement and the characteristic of flow stress were analyzed. The results indicate that the flow stress decreases with increasing temperature and decreasing strain rate. The constitutive relationship of TB10 alloy is obtained on the base of Arrhenius equations.
