Modeling of texture evolution in the deformation zone of second-phase particles
چکیده انگلیسی

Cast aluminum alloys usually contain coarse constituents which are likely to serve as potential nucleation sites during recrystallization. In the course of deformation a special zone develops around such non-deformable particles, which is characterized by a high local strain and high misorientation gradient. This makes them preferred nucleation sites for recrystallization during a subsequent heat treatment. The orientations of such nucleation sites are of importance for the recrystallization textures. The aim of this study was to investigate the evolution of the microtexture within the deformation zone. For plane strain compression the strain distribution around particles was modeled by means of the finite element method (FEM). For spherical and cuboidal particles the local displacement gradients were used to compute the deformation texture by a Taylor type model. The predicted textures were compared to published experimental data.
