Abstract
A model for the age hardening response in 7475 aluminium alloy has bee n developed that describes the effect of two step aging treatments and the effect of deformation on the kinetics of aging. The model describ es the essence of the experimental observations on the alloy subjected to deformation before artificial aging, i.e. the occurrence of the pe ak stress at shorter times, the acceleration of the kinetics of overag ing, and the change in the relative yield stresses between the alloy w ith and without deformation during aging.
