| Outline of Final Research Achievements |
Recently, development of lightweight and high-strength steel by controlling its underlying microstructures is desired. In particular, in order to develop new high strength steels efficiently, numerical simulation techniques based on computational materials science which enables us to predict the mechanical properties of the steels from their microstructure have been actively studied. In this study, we have developed the numerical simulation methods to predict the microstructure evolutions in steels and aluminum alloys by the multi-phase-field method, and to evaluate the morphology of the predicted microstructures. Furthermore, the numerical material test and the sheet metal forming simulation techniques based on the crystal plasticity finite element method were established. We have discussed the possibility of numerical microstructure optimization for improving the mechanical properties and formability of steels and aluminum alloys by combining above-mentioned simulation methods.
