Outline of Final Research Achievements

Material development methodology called Reverse 4D Material Engineering (R4ME) has been established. We have divided the optimization targets into two cases; "microstructure cluster control" and "single microstructure control" to make R4ME applicable to various issues in the materials and mechanical engineering. In particular, we have created a data coarsening method, optimization method and R4ME methodology appropriate for adapting them. We have shown that R4ME enables to use the information about a huge number of microstructural features embedded in one high-resolution 3D image as big data. The optimization of polycrystalline microstructure is also possible by employing the polycrystalline imaging technique.
