The deformation behavior and processing maps in the isothermal compression of 7A09 aluminum alloy

Isothermal compression tests of 7A09 aluminum alloy were carried out on a Gleeble-1500 simulator at the deformation temperatures ranging from 633K to 733K, the strain rates ranging from 0.01s−1 to 10.0s−1, and the height reductions ranging from 40% to 85%. Several modeling approaches, including the flow stress–strain curves, the kinetic analysis, the constitutive model and the processing maps, are used to characterize the deformation behavior …
