Enhanced Mechanical and Electrical Properties of a Cu-Ni-Si Alloy by Thermo-mechanical Processing

Two different thermo-mechanical processing routes, single-cold-rolling and double-cold-rolling, are adopted to process a Cu-Ni-Si alloy, and their effects on the microstructure and properties of the alloys are investigated. While keeping identical aging treatments and equivalent total cold-rolling deformation, 45-minute final aging at 450 °C endows the double-cold-rolling-processed alloys with a tensile strength of 754 ± 12 MPa, higher than...
