Abstract Discontinuous subgrain growth is an important mechanism for the formation of recrystallization nuclei during annealing after cold rolling aluminum alloys. Based on analytical textbook theory continuous and discontinuous cellular microstructures, we derive validate simple mean-field criteria onset in The determining factors are stored energy deformation, rate recovery mobility large angle grain boundaries. successfully applied to isothermal annealings at constant heating rates. They...
Abstract The influence of strain rate sensitivity on development Cube texture and the morphology Cube-oriented grains is often neglected in simulations approaches. Therefore, crystal plasticity experiments were performed up to 73 pct thickness reduction for cold rolling Al 6016. It found, that low values promote fragmentation avoid formation transition bands already at 50 55 reduction. High strain-rate cause leaving thin microstructure delay their fragmentation. Other components are affected...
