Influence of stacking fault energy and short-range ordering on dynamic recovery and work hardening behavior of copper alloys

Abstract

True stress vs. true strain responses of Cu–6 wt.% Al and Cu–12 wt.% Mn alloys are presented. While Cu–6 wt.% Al alloy shows the typical mechanical response of low stacking fault energy alloys, the Cu–12 wt.% Mn alloy behaved similarly to medium to high stacking fault energy alloys. These findings clearly show that while short-range ordering triggers slip planarity, it has a minor effect on total dynamic recovery of these copper alloys.
