| Research Abstract |
Complex microstructures of advanced structural materials are investigated by a multi-scale analysis by transmission/scanning electron microscopy combined with X-ray diffraction to reveal their deformation mechanisms. A laminated steel with hard/ductile steel layers have been investigated particularly focusing on the lath, block, and packet structures of the hard martensite steel layers. The contributions of the lath and coarser scale structures to the tensile deformation behaviors are discussed on the basis of the observed microstructures. Furthermore, it is indicated that the ductile steel layers act as a buffer for strain accumulation in the hard steel layers.
