The objective of this work is to develop a physically-based understanding and description of the response of an AA7050 alloy (Al-Zn-Mg-Cu) during high temperature thermomechanical processes, specifically hot rolling. Differential scanning calorimetry is used to determine the thermal stability of the precipitate phases, which have been identified by electron microscopy. Microstructural characterization is employed to determine the change in the microstructure and deformation behavior as a function of temperature. This information is used to interpret data from high temperature compression tests performed to high strains. The compression test data are fitted to a constitutive model that characterizes yield and saturation stress. Finally, the derived constitutive model is implemented as a user-subroutine in a commercial finite element code to simulate the rolling process.
