It has been reported that the reloading flow stress overshoots the monotonically loaded flow stress as a transient hardening behavior when a certain metallic materials are unloaded after prior plastic strains and subsequently reloaded. This phenomenon has been called as the “unloading yield effect (UYE)” and many researchers have tried to explicate such effect through Cottrell atmosphere, dislocation-dislocation interaction, dislocation-precipitate interaction and non-uniform flow stress distribution.
In this presentation, the UYE in 7075 aluminum alloy sheet is investigated based on the concept of dislocation-precipitate interaction. Artificially aged 7075 aluminum alloys with various aging times were pre-strained, unload ... 전체 초록 보기
