摘要
The microstructure evolution and the change of Burgers orientation relationship between alpha and beta phase of TC17 titanium alloy with initial lamellar microstructure were researched by EBSD. The results show that dynamic recrystallization of beta phase occurs during the hot deformation process. Meanwhile, the dynamic globularization of alpha phase includes the formation of subboundary and the fragmentation of alpha phase. The fragmentized alpha phase eventually transforms to globularized particle. In addition, the strict Burgers orientation relationship between alpha and beta phase is destroyed, due to the activation of prismatic slip system and other slip or twin systems.
