Microstructure and second-phase strengthening mechanisms of CuTeCrY alloy
A CuTeCrY alloy prepared by homogenising annealing, hot extrusion, solution treatment, cold drawing, and a heat ageing treatment has tensile strength and electrical conductivity of 430 MPa and 78.9% IACS, respectively. Electron microscopy analyses show that a metastable CrCu2Te phase in the solid solution alloy is eliminated by the ageing treatment, and a 3–5 nm granular bcc-Cr phase becomes distributed in the matrix. This nanometre Cr second phase is the main contributor to the strengthening of the alloy whereas the second-phase strengthening effects of micrometre Cr and Te phases are weak.
