Abstract

Quaternary Zr₄₇Cu₄₀Al₁₀M₃ (M: IVA ∼ VIA), Zr₅₀Cu₃₇Al₁₀M₃ (M: VIIA ∼ IB), and Zr₅₀Cu₄₀Al₇M₃ (M: IIB∼) bulk glass alloys (BGAs) were examined to clarify the glassy structure of Zr₅₀Cu₄₀Al₁₀ BGA. The glass structural difference was evaluated by the volume change due to structural relaxation at the glass-transition temperature (T_g); the volume shrinkage was estimated using density measurement. The results indicated that Pd, Ag, Pt, and Au, which are characterized by a filled d-shell electron structure, are effective for enhancing volume expansion in a glass structure. Furthermore, the volume changes in quaternary Zr-Cu-Al-M BGAs could be classified into two groups. This implies a difference in glass structure between the Zr₅₀Cu₃₇Al₁₀M₃ (M = Pd, Ag, Pt, and Au) BGA and others examined in this study.
