Pre-aging combined with multi-stage rolling processing: Enhancing precipitate-dislocation interaction for strengthening of Cu-Cr-Zr-Ni-Si alloy

The low strength of high-conductivity Cu-Cr-Zr alloys has restricted their application in micro-structural lead frames. This study introduces pre-aging multi-stage rolling processes to generate high-density dislocations via pre-precipitated Cr phases in a Cu-Cr-Zr-Ni-Si alloy, enhancing its hardenin...
