Recrystallization microstructure modelling from superimposed deformed microstructure on microstructure model

摘要

The recovered cold rolled microstructure obtained from orientation image microstructure of Al-4%Mg-0·5%Mn alloy (AA5182 alloy) was superimposed on the grid of cellular automata based microstructure model. The Taylor factors of deformed/cold rolled orientations were considered as the driving force for recrystallization. The local development of recrystallized microstructure and texture were simulated with orientation dependent grain boundary mobility and compared with the experimental results.
