Abstract
The deformation response and texture evolution of aluminum alloyed Hadfield steel polycrystals is explored in the presence of high-density dislocation walls. A recently developed visco-plastic self-consistent model accounting for the contribution of the dense dislocation walls to strain hardening was utilized in predicting the room temperature deformation response under tension and the accompanying texture evolution. The model successfully predicted the experimental results, demonstrating the utility of the model for polycrystals. Monitoring the texture evolution provided an independent check and validation of the model.
