Prior studies of as-cast AA7050 mechanical property are sparse, and the mechanical properties are usually measured with uniaxial tensile tests. In order to generate data for simulation of stress development in direct chill (DC) casting, compression tests were performed on AA7050 samples in both as-cast and homogenized conditions in the temperature range of 20 to 500 °C at strain rates from 10<SUP>-4</SUP> to 10<SUP>-2</SUP>/s to strains of ~0.5. Results from test specimens having round and square cross-sections with L/D = 1.5 were compared to each other and to published tensile data. The flow stress-strain data is fit to the Ludwik equation to generate constitutive laws for the flow stress as a function of strain, strain rate and temperature. The effect of microstructural changes from as-cast to homogenized structures on mechanical properties is discussed.
