Abstract

The paper describes the process of creating a rheological model of aluminum alloy 1163, intended for use in software packages for modeling metal forming processes. The flow stress curves of the alloy depending on the temperature and strain rate were obtained experimentally. Using the empirical Hensel-Spittel model, the coefficients determining the dependence of the flow stress on the thermomechanical parameters were calculated. The resulting model ensures high convergence of the calculated and experimental data.
