摘要：

The effect of electropulsing treatment (EPT) on properties, microstructures and texture of the cold-rolled Cu strips is investigated by electron back scattered diffraction (EBSD). The results show that the elongation of Cu strips increases while the Vickers hardness and electrical resistivity drop with the increase of the frequency of electropulsing excluding 600 Hz. The grain size increased with increasing the frequency of electropulsing. The frequency of coincident site lattice (CSL) and twin reach the maximum using the EPT of 400 Hz. In addition, the change of microstructure induced by EPT strengthens P{011}< 12 (2) over bar > orientation and weakens S{123}< 63 (4) over bar > and Bs{110}< 1 (1) over bar2 > texture component content. The twin formation and crystallization mechanism of the cold deformed Cu under electropulsing are proposed. (C) 2012 Elsevier B.V. All rights reserved.
