The effect of nucleation models on dynamic recrystallization II. Heterogeneous stored-energy distribution

摘要: Abstract An efficient Monte Carlo procedure is applied to the study of dynamic recrystallization in polycrystals. The approach essentially same as part I this series papers and consists representing microstructure by a discrete two-dimensional lattice. crystallographic orientation each lattice element its neighbours determines position grain boundaries their energies. Hot deformation modelled adding nuclei stored energy continuously with time. Nucleation introducing three-site nucleus represented two generic types model: either random nucleation or preferential regions high energy. energy-storage-rate schedule was used model both work hardening recovery metals way stage III work-hardening law. novel taken paper non-uniform substructure using mean cell size L distance R...
