Crystal plasticity and continuum mechanics-based modelling of deformation and recrystallization textures in aluminum alloys

摘要

This contribution provides a brief overview on modeling the deformation textures by combining both crystal plasticity approaches and models based on principles of continuum mechanics, dealing with a flow of a material during deformation. The behavior of Al alloys during deformation is analyzed by means of well-established crystal plasticity theories such as full constraints Taylor, advanced Lamel, visco-plastic self-consistent and Cluster V model. As a first approximation, the deformation flow in rolling is approximated by plane strain compression, however, it is shown that an improvement in texture prediction is reached by considering strain heterogeneities, evolved across the thickness of a rolled sheet. The effective modeling strategies employed in texture simulations are discussed in the current contribution. It is analyzed how microstructural heterogeneities might influence the evolution of recrystallization texture and plastic strain ratio in aluminum alloys.
