为了考察5A05铝合金高温拉伸时的再结晶过程,用高温金相显微镜,对其在高温热变形时的动态变化进行观察,发现5A05铝合金在高温热变形时发生了动态再结晶,并且产生了空洞,发生了晶粒滑移和晶体转动,为开展超塑性机理的研究提供了试验设备.
In order to investigate the recrystallization process of 5A05 aluminum alloy during high-temperature drawing, the dynamic changes of 5A05 aluminum alloy during hot deformation at high temperature were observed by high-temperature optical microscope. It was found that dynamic recrystallization of 5A05 aluminum alloy occurred during hot deformation at high temperature, The hollow, the occurrence of grain slip and crystal rotation, in order to carry out research on the superplastic mechanism to provide a test equipment.
