Outline of Final Research Achievements

The effect of low-temperature thermal cycling method on dynamic stress relaxation behavior was investigated for Nd- and La-based metallic glasses. No significant changes in peak temperature were observed in the relaxation region as the low-temperature thermal cycling treatment progressed. Furthermore, the effects of low-temperature thermal cycling on the tensile strength and plastic elongation of ABS resin were investigated. It was found that low-temperature thermal cycling did not significantly change the tensile strength and plastic elongation of ABS resin. These results suggest that the ductility enhancement by the low-temperature thermal cycling method does not originate from inhomogeneity in the glass structure.

Academic Significance and Societal Importance of the Research Achievements

金属ガラスに限らずガラス物質の構造や形成過程は長い歴史の中で十分に理解されてこなかった経緯がある.本研究成果はガラス構造と機械的性質の関係性について一定の知見を与えると考えている.
