Surface structures and crystalline microstructures are the key factors to control surface functions. Through the combination of plastic deformation and heat treatment, it is possible to fabricate surfaces with predesigned textures and thus gain control of surface functions. However, the link between metals in deformed state and the resulting microstructure after annealing remains uncovered. In this work, plastic deformation through tensile test and following static recrystallization in annealing are carefully studied. In-situ observations were performed to trace the microstructure evolution during annealing. The results have shown that the nucleation tend to happen at sites with largest strain gradient and the grain boundary generally migrated along [110] planes in grain growth. These preliminary conclusions may help to control surfaces microstructure for development of functional surfaces.
