Abstract

In this paper, flow stress of Al6061 is obtained by compression test in the range of temperature from $300^{\circ}C$ to $550^{\circ}C$ and effective strain-rate from 0.1/s to 20.0/s. The flow stress information is used to simulate an aluminum hot forging process. Non-isothermal simulation is carried out by a rigid-thermoviscoplastic finite element method. The predictions are compared with the experiments in terms of the deformed shape of material.
