| Abstract Scope |
Recrystallization texture evolution in recycled aluminium alloys containing coarse intermetallic particles is controlled by the interplay between microchemistry and deformation heterogeneities, such as particle deformation zones (PDZs). During cold rolling, plastic strain localization around non-deformable constituent particles leads to the development of sharp orientation gradients and locally increased stored energy. These conditions favour particle-stimulated nucleation (PSN), while growth is governed by the local competition among subgrain coarsening, precipitation kinetics, and orientation-dependent Smith–Zener pinning by dispersoids. This work presents a coupled crystal plasticity cellular automata workflow for modelling recrystallization texture formation in a particle-containing Al–Mn–Fe–Si alloy. High-resolution CPFFT resolves deformation heterogeneities at the subgrain level, and the regridded orientation field drives curvature-driven abnormal subgrain growth in the CA model. PSN-related P {011}<566> and Cube ND {001}<310> components emerging from PDZs are captured, thus establishing a predictive through-process modelling framework. |
