私たちの生活を支える鉄鋼材料をはじめとする多様な金属材料。本研究室ではその性能を，材料組織をナノ・ミクロ・マクロの様々なスケールで制御し，さらに複合化や複層化，微細化を重畳することによって飛躍的に向上させ，革新的な鉄鋼材料や新たな金属材料の創製を目指しています。そのためのマルチスケールの組織の形成機構の解明や制御，ならびに，組織の形成起点や複合化・複層化，さらに異種材料接合の鍵となる異相・異材の界面の解明と制御の研究を進めています。

Many metallic materials based on steels are essential to supporting us in our everyday lives. At our laboratory, we endeavor to control the structures of such materials on the nano, micro and macro scale, by forming composites and multilayered structures, while refining their microstructures. Through these techniques, we aim for rapid performance advancement, and to discover new innovative steels and metals. We carry out research on these multiscale structures, identifying and controlling the formation mechanisms and formation origins of phases, composite formation, as well as the bonding of dissimilar materials. The key to these processes in to which we are researching is clarifying and controlling the nature of the interfaces between different phases and different materials.

High Performance Multilayered Metallic Materials and Composites

High strength components and high ductility layers are used in order to implement super-high strength as well as high ductility. The process, structure, thermodynamic properties are being controlled, and deformation behaviour is being clarified.

Mechanisms of Displacive Phase Transformations in Steels

In order to control the structure of martensite and bainite, the key phases in enhancing strength in steels, we aim to clarify and control the structural formation mechanisms of the transformations of these phases.

Clarification of the Hetero-Interface Bonding Mechanisms

High strength steels and dissimilar materials have until now been extremely difficult to weld. In order to make this bonding possible, we are developing new low-temperature, short-time bonding techniques and clarifying interface growth mechanisms of such processes.
