Recrystallization and grain growth process is one of the most important physical metallurgical processes to produce metal materials. After long time basic studies, a lot of achievements have been got, such as Directional Nucleation and Selective Growth Theory, Phenomenological Theory. But there are still many problems in explanation of recrystallization microstructure evolution. The traditional approach to research the recrystallization and grain growth of material is metallographical observation .This appr...
