Abstract:The physically-based hardening formulation was derived from dislocation theory resulting in both statistical and geometrical storage components, where the distinguishing microstructural length scales were included in the geometrical storage terms. The phenomenon of precipitation-induced anisotropy was incorporated into the hardening description. Model results were compared to single crystal and polycrystal compression experiments. Accurate simulations were obtained for most of the aging conditions and the correct trends due to precipitate-induced anisotropy were predicted.
