Enhanced Grain Refinement by Mechanical Twinning in a Bulk Cu-30 mass%Zn during Multi-Directional Forging

A bulk Cu-Zn alloy was multi-directionally forged at 77 K and 300 K to a cumulative strain of ΣΔe = 6.0. With increasing strain, the initial grains subdivided gradually to ultrafine grains. Mechanical twins enhanced the grain fragmentation. The formed twins were further subdivided by the other variants of twins. The grain size obtained at ΣΔe = 6.0 was about 17nm at 77 K and 26nm at 300 K.
