Outline of Final Research Achievements

We develop a new heating-quenching process above the glass transition temperature and establish a technique for controlling the relaxation state by introducing non-affine strain in metallic glass. In particular, the introduction of the gradient relaxation state distribution in the radial direction of the cylindrical sample announced in 2020 provides a novel material control method that renews the conventional wisdom of metallic glass materials. By such material control, we succeeded in producing a metallic glass showing excellent plastic deformability (toughness). In addition, structural evaluation by molecular dynamics simulations revealed structural changes at the atomic level due to the introduction of non-affine strains, and was able to elucidate the mechanism of relaxation state control and construct the theory.

Academic Significance and Societal Importance of the Research Achievements

金属ガラスは原子が規則正しく配列する結晶構造を有しない金属で、結晶材料にはない様々な新規な特性を有する。しかしながら金属ガラスでは、加工等によって起こる原子レベルでの微小な構造変化(緩和)によって有用な特性が失われるという問題があった。そして一旦緩和が起きてしまうと、容易にはもとに戻せないということが知られていた。本研究課題は緩和状態を意図的に制御(回復)し、有用な特性の維持、回復、発現を目指す全く新しい構造制御法を確立したもので、材料科学の発展に大きく寄与するものと考えられる。
