Uniaxial tensile deformation behavior of 7075-T6 under three different strain rates (0.001, 0.004 and 0.03s-1) and five different temperatures (50, 100, 150, 200 and 250°C) is studied. The total elongation in uniaxial tension increases with increasing temperature in range of 50-200°C and decreases with increasing strain rate. But it drops sharply at 250°C. SEM observations of the fracture surface interpret the change of total elongation and show the fracture tends to transit from brittle mode to ductile mode with increasing temperature. The constitutive model and yield function related with temperature are established based on the experiment results.
