(J023)Simultaneous increment of strength and ductility by Thermo-Mechanical Processing in harmonic structure designed pure copper

摘要

Harmonic structure (HS), consisting of continuous connected “shell” (ultrafine-grainedareas) and “core” (coarse-grained areas), has become one of effective approaches to achieveboth high strength and high ductility simultaneously by the enhancement of strain hardeningability. The effect of thermo-mechanical processing (cold rolling and annealing process) onthe microstructure and mechanical properties of harmonic structure pure copper was investigatedin present work.
