Equi-Plastic Work Locus of 5000 Series Aluminum Alloy Sheet at Warm Temperature

Abstract:

Warm temperature biaxial stretching equipment was developed in order to observe equi-plastic work locus at elevated temperature. A thermostatic bath is installed in the conventional biaxial stretching machine, and a heat gun and an electric heater in the bath enable to heat the specimen up to 260°C. Since flow stress is affected by strain rate at warm temperature, the equipment enables stress ratio and strain rate controls at the same time. Equi-plastic work loci of AA5182-O was obtained by the developed apparatus at R.T., 170 and 260°C, and temperature dependence on biaxial deformation was discussed.
