摘要：

Complex dynamic and static softening behaviors in flow stress evolutions serve as important indicator for optimizing the power or load required by thermomechanical processes of Al-Cu-Mg alloys. However, the flow stress behaviors during the commonly employed industrial multi-stage warm and hot forming of Al-Cu-Mg alloys are rarely reported. In this work, therefore, the complicated flow hardening or softening mechanisms during multi-stage warm (200 ºC) and hot (300 ºC and 400 ºC) deformation of the air-cooled (AC) and water-quenched (WQ) Al-Cu...
