Texture Evolution of Commercially Pure Copper during Ultra-Thin Strip Rolling

Article Preview

Abstract:

Experimental investigation on rolling texture evolution in commercially pure copper thinned from 5.8mm to 20μm by symmetrical rolling and asymmetrical rolling without annealing were carried out via orientation distribution functions and orientation line analysis. The results show that the rolling texture for the sample with initial rotate cube texture {100}<011>mainly consist of C and B, most crystallites aggregate along the α and β orientations lines. The texture density growth rate increased significantly in rolling process. That may relate to size effect of ultra-thin strip. The rate of dislocation reduction was more than dislocation multiplication due to disappear at grain size, when the thickness of ultra-thin strip decreased to an extremely value.
