中文摘要：

采用热模拟试验机对Ti-5Al-5Mo-5V-1Cr-1Fe合金进行等温压缩试验,获得变形温度为750~900℃和应变速率为0.001~1 s 1时的真应力真应变曲线,并运用修正后的试验数据建立真应变为0.7的热加工图。通过显微组织观察,分析合金的变形机理,确定热变形失稳区。研究结果表明：Ti-5Al-5Mo-5V-1Cr-1Fe合金加工温度范围较宽,当加工温度低于800℃且变形速率大于0.1 s 1时易发生绝热剪切,造成流变失稳;随着变形温度升高,功率耗散因子η有增大趋势,合金的流动软化机制由动态回复逐渐变为动态再结晶,显微组织也随之细化、均匀。

英文摘要：

The hot deformation characteristics of Ti-5A1-5Mo-5V-1Cr-IFe alloy were investigated between 750-900 ℃ and strain rate range of 0.01-1 s-1 through hot compression tests. The processing map at strain of 0.7 was given according to the corrected data of true stress-strain curves, and the microstructures of deformed specimens were observed. The region of deformation instability and deformation mechanism was abtained from the map. The results show that Ti-5A1-5Mo-5V-1Cr-IFe alloy can be processed in a large temperature range, while adiabatic shear appears at relatively low temperature （〈800 ℃） and high strain rate （〉0.1 s-l）. The power dissipation factor increases with the increase of the temperature, the deformation mechanism transforms from dynamic recovery to dynamic recrystaUization, and the microscopic structure of the alloy is more uniform.
