Textural evaluation of copper produced by equal channel angular pressing with routes A and B30
چکیده انگلیسی

The present study investigated texture evolution and tensile properties of oxygen-free, high conductivity copper (OFHC) subjected to equal channel angular extrusion at room temperature for up to ten passes using routes A and B30. As the cross sections of the specimens were circular, a new route with a rotation angle of 30° in the same direction between consecutive passes was used. Texture was weak in the initial copper specimen. Both routes exhibited texture development similar to simple shear. In route A, A1 and C are the main components up to four passes and the B/B¯ components strengthen in the sixth pass, but in route B30 the discontinuous strain path applied to the bar through rotation by 30° around its longitudinal axis between each pass results in significant changes in texture with increasing N. The tensile strength and ductility of the annealed and ECAP samples with routes A and B30 were measured using tensile tests and the relations between tensile strength and intensity of (1 1 0) textures were obtained.

Research highlightsA new route with a rotating angle of 30° in the same direction between consecutive passes was adopted and comparisons were made between the texture evolutions of pure copper specimens processed by CAP up to ten passes with routes A and B30.
