Cold-rolled IF steel was treated by surface mechanical attrition,and a gradient structure with grain size varing from nano-scale to micro-scale was obtained.The structure,texture and properties were examined by using different techniques.Experimental results show that the surface nanocrystallization of cold-rolled IF steel is documented by dislocation activities,the existence of textures can't affect the grain refinement behaviours.With the increment of misorientations in the grain refinement process,the te...
