Effect of intermediate-heat treatment on the nanotructure and mechanical properties of Cu-15％Ag by ECAP (equal channel angular pressing)
INTRODUCTION High-strength, high-conductivity materials are very important for the construction of high-field magnets. The development of those high-field magnets has been limited by the quality of conductor material, which requires both high strength to resist the Lorentz force and high conductivity to suppress Joule heating 1-6. There are three established approaches for strengthening alloy, I.e. Solid solution hardening, precipitation hardening and work hardening. Typically element addition to the matrix strengthens the alloy but reduces its conductivity 1-6. However, the combination of work-hardening and precipitation hardening can lead to hardening without a large drop in conductivity. Deformation processing such as drawing or rolling has been employed to refine the microstructure, which leads a fine or even nano-scale two-phase microstructure with strong crystallographic textures.
