COMPUTER MODELLING OF DEFORMATION AND ANNEALING PROCESSES AND THEIR INDUSTRIAL APPLICATIONS
Computer models have been developed to simulate texture and microstructure transformations during deformation, recrystallization and grain growth processes. The deformation model takes into account not only crystal plasticity, but also grain boundary sliding and superplastic deformation. The recrystallization and grain growth models are developed based on microstructural description of polycrystalline materials and simulated with Monte Carlo techniques. The computer models incorporate many structural characteristics of polycrystalline materials such as, texture, grain boundary structure, grain shape and size, phase composition, chemical composition and stored elastic energy. The ultimate goal of current work is to visualize the deformation and annealing processes of metal and to help researchers and engineers understanding and optimizing the manufacturing process. In the results of simulation of deformation and annealing process of various steels are presented as examples.
