在不同温度下对TC11钛合金进行了压缩实验,采用金相显微镜观察了其变形后的显微组织,并利用扫描电子显微镜对其不同变形程度变形后的显微组织进行了观察.结果发现,在较低温度下变形时在晶界处发生了动态再结晶组织,在1000℃时显微组织以动态再结晶晶粒为主,当温度达到1050℃时合金组织中再结晶晶粒相互长大,呈等轴状.%Compression test of TC11 titanium alloy have been carried out on various temperatures, and microstructure evolvement of TC11 titanium alloy has been observed by use of the optics microscope (OM) and scanning electron microscope (SEM) in various forming content and forming temperature. The test result shows that dynamic re-crystallization has been found in crystal interface at lower temperature. The dynamic re -crystallization grains are preferential at the temperature of 100℃ while the re-crystallization grains become bigger and equal-axis shape at temperature of 1050℃.
