本文采用光学金相和电子金相试验方法,研究了TC6合金的动态再结晶,作出了变形温度、变形度和晶粒大小的三维动态再结晶图,确定了获得均匀、细小的等轴β晶粒的热变形工艺参数,并试图以静态再结晶理论对试验结果进行了定性的讨论。
An investigation was made of the dynamic recrystallization of TC6 Ti alloy by optical microscope and TEM. The three-dimensional dynamic recrystallization diagram of the alloy was establisbed and the optimum hot-deformation parameters for a uniform and fine size grain were determined. An discussion on the experimental results together with the static recrystallization theory is described.
