Temperature Evolution and Optimization of Hot Extrusion Process for Al-Zn-Mg-Cu Aluminium Alloy Based on FEM Simulation

Abstract:

Hot extrusion process of Al-Zn-Mg-Cu alloy billet had been simulated under different temperature of billet and container. It was proposed that due to large deformation and friction, maximum temperature of the billet occurs on the skin near extrusion export and is under three direction tension stress state, where surface is likely to crack if temperature surpassed the incipient melting point. The right temperature of the billet and container is 425°C~450°C and 400°C respectively with the constant extrusion speed 0.8mm/s
