The flow behavior and constitutive equations in isothermal compression of 7050 aluminum alloy

The flow behavior of 7050 aluminum alloy was investigated by means of isothermal compression tests. Isothermal compression of 7050 aluminum alloy was carried out on a Gleeble-1500 thermal simulation machine at the deformation temperatures ranging from 593K to 743K, the strain rates ranging from 0.01s−1 to 20.0s−1, and the height reductions of 30%, 50% and 70%. The characteristics of stress–strain curves are determined by the interaction of work …
