Additive Manufacturing Group
Group Introduction
Research Overview
Regarding 3D additive manufacturing processes capable of directly creating complex three-dimensional structures from raw powder, we are advancing research on the correlations among process conditions, material microstructure, and properties from both experimental and computational prediction perspectives. Targeting a variety of structural materials—Ni-based alloys (Hastelloy X, Inconel 738LC, etc.), Ti alloys (Ti-6Al-4V, Ti-Nb), heat-resistant steels (modified 9Cr-1Mo steel), stainless steels, and others—we are working to establish microstructure control techniques unique to 3D fabrication and to optimize mechanical properties. Furthermore, based on these findings, we are also taking on the development of new materials suitable for 3D fabrication. In addition, we are researching thermal spray coatings to protect components from harsh environments and nondestructive evaluation technologies to ensure reliability.
