Abstract:
The dynamic compression experiments of ZL101A aluminum alloy were carried out under room and high temperature conditions by using split Hopkinson pressure bar (SHPB) system and high temperature heating equipment. The dynamic compressive stress-strain curves under the conditions of strain rate range of 2900−6100 s−1 and temperature range of 20−600 ℃ were obtained. The experimental results show that ZL101A aluminum alloy has a strain rate hardening effect, and the strain rate hardening effect gradually decreases with the increase of temperature. Meanwhile, ZL101A aluminum alloy has obvious temperature softening effect at different strain rates, and the plastic deformation induced adiabatic temperature rise enhances the thermal softening effect. In order to quantify the influences of strain rate and temperature on the flow stress of ZL101A aluminum alloy, the strain rate effect and the temperature effect were decoupled. A suitable constitutive model for ZL101A aluminum alloy was established by analyzing and fitting the experimental data. After comparing the predicted results from the model with the experimental data, it was found that the established constitutive model can well describe the flow stress characteristics of ZL101A aluminum alloy.
