Abstract

This paper is intended to investigate the effect of additional solute elements on the glass-forming ability by studying the crystallization processes of Cu₄₀Ti₃₀Ni₁₅Zr₁₀Sn₅ and Zr₆₀Ni₂₅Al₁₅ amorphous alloys in the supercooled liquid region. The crystallization of Cu₄₀Ti₃₀Ni₁₅Zr₁₀Sn₅ amorphous alloy takes place through the reactions of Am → CuTi + Cu₁₀Zr₇ → Cu₁₀Zr₇ + Cu₃Ti + CuTi₂ + Cu₂Ti. Enrichment of Sn in the Cu₁₀Zr₇ phase was revealed by compositional analysis. On the other hand, the crystallization of Zr₆₀Ni₂₅Al₁₅ amorphous alloy takes place through the reaction of Am → Zr₅Ni₄Al + Zr₆NiAl₂. The common feature in the crystallization processes of the two alloys is the necessity of significant redistribution of the solute elements (Sn or Al), which is believed to play an important role in the stability of the supercooled liquid against crystallization.
