Comparative investigation on the modified Zerilli-Armstrong model and Arrhenius-type model to predict the elevated-temperature flow behaviour of 7050 aluminium alloy

► 7050 Aluminium alloy flow behaviour study using modified ZA and Arrhenius model. ► Compensation strain Arrhenius model prediction displayed a better accuracy track. ► Coupled deformation-heating effect was weak for 7050 aluminium alloy.
