Evolution of recrystallization textures in particle containing Al alloys after various rolling reductions: Experimental study and modeling

Abstract The presence of large elastic constituent particles in aluminum alloys triggers strain heterogeneities in rolled materials. Finite element calculations demonstrate that the strain field in the vicinity of non-deformable particles strongly deviates from the macroscopic one, which induces a specific texture in the particle affected deformation zone during recrystallization. Results of the current study reveal that after various degrees of rolling reduction the corresponding recrystallization textures show significant qualitative and quantitative differences with respect to each other. The evolution of recrystallization textures is explained by a model which combines both orientation selection during nucleation and micro-growth selection. The current texture simulation provides very satisfactory results and suggests that the evolution of the {1 0 0}〈1 3 0〉 and {0 11 }〈2 3 3〉 components in recrystallized materials is related to the well-known particle stimulated nucleation mechanism.
