The flow behavior and constitutive equations in isothermal compression of 7050 aluminum alloy

► Flow behavior and microstructure were influenced by strain rate remarkably. ► DRX takes place easily at larger strain and higher deformation temperatures. ► Constitutive equations in this paper can characterize DRV and DRX. ► The equations can predict the flow behavior during whole deformation process. ► The equations consider the deformation heating, and the relative error is 5.73%.
