چکیده انگلیسی
Surface mechanical attrition treatment (SMAT) is an innovative technique which can produce nanocrystalline (nc) layers of several tens of micrometers thickness on surfaces of metallic materials. In this work, the grade structures of commercially pure titanium (CP Ti) processed by SMAT was studied intensively, and the microstructure observations indicated that the dislocation evolution could be separated into three steps: (1) formation of dislocation tangles; (2) formation of dislocation bands; and (3) dynamic recrystallization of dislocation bands until the formation of nc Ti.
