Hot compression tests of 7075 aluminum alloy were carried out on the Gleeble-1500 thermal simulation machine at strain rates of 0.01 s-1 ,0.1s-1, 1s-1 and at temperatures of 320°C,400°C,480°C. The compression direction are aligned at 0°and 45°to the axis direction of the bar. Microstructure was studied using Optical Microscopy. The results show that the true stress of both specimen increases with the decrease of temperature and the increase of strain rates. The true stresses rose rapidly to peak value and then held constant or decreased with the increase of the true strains at different deformation conditions. The yield strength and stable flow stress of the specimens in 0° to the axis direction is higher than that of 45° specimen, which could be attributed to the elongated grain structures of the bar and the texture of the extruded bar.
