  • Warm tensile tests for high strength aluminum alloy 7B04-T6 sheet were held at condition of elevated temperature and different strain rates. The range of temperature is 293~573K and the strain rate is 0.0006~0.06s-1. The warm tensile properties, relation between temperature, strain rate and the flow stress were discussed. It is concluded that flow stress decline with the increase of temperature and the decrease of strain rates; Elongation percentage increase with the increase of temperature and the decrease of strain rates. Furthermore constitutive equations under warm tension were obtained based on Fields and Backofen equation.
