研究概要

原料粉末から複雑な三次元構造を直接作成可能な3D積層造形プロセスについて、プロセス条件と材料組織、特性の相関について、実験および計算による予測の両面から研究を進めています。Ni基合金 (ハステロイX、Inconel 738LC等) や、Ti合金(Ti-6Al-4V、Ti-Nb)、耐熱鋼 (改良9Cr-1Mo鋼) 、ステンレス等、様々な構造材料を対象として、3D造形ならではの組織制御技術の確立や力学特性の最適化に取り組んでいます。さらに、これらの知見に基づいて、3D造形に適した新しい材料開発にも挑戦しています。この他にも、過酷な環境から部材を保護するための溶射コーティングや、信頼性確保のための非破壊評価技術についても研究しています。
