摘要：
Effect of combined processing by the equal-channel angular hydroextrusion (ECAH), direct hydroextrusion (HE) and drawing (D) on properties of copper wire is discussed in the paper. The technique has been for the first time employed for hardening lengthy copper rods and wire and reaching the ultimate tensile strength sigma = 686 MPa and the elongation to failure delta = 2% in the 0.5 mm diameter copper wire. These contrast with sigma = 556 MPa and delta = 1.4% resulted from processing without ECAH. Electrical conductivity of the highest strength wire produced with ECAH and conductivity of a hardened wire produced without ECAH differ negligibly. (C) 2010 Elsevier B.V. All rights reserved.
