Abstract

The deformation behavior of aluminum alloy 5052 is studied by isothermal hot compression in a wide range of temperatures ranging from 300 °C to 450 °C and strain rates ranging from 0.01 s-1 to 1 s-1. The results show that the peak stress increases with the strain rate while decreases with the temperature. In the early stage of deformation, the stress increases with the strain to peak stress, while decreases with softening. In this paper, the flow behavior is modeled by a liner function including the peak stress and stress softening rate respect to strain. The effect of strain rate and temperature on the peak flow stress was established by the Arrhenius-type equation. The softening rate was modeled empirically by a multiple linear function of strain rate and temperature. The model parameters were obtained by regressions. The constitutive model was verified and good agreement was achieved.
