Abstract

The primary precipitation phase for the Hf₆₂Al₁₀Ni₈Cu₂₀ metallic glass is face centered cubic (FCC)-Hf₂Ni and those for Hf₅₇Al₁₀Ni₈Cu₂₀Ti₅ are FCC-Hf₂Ni and I-phase. Addition of Ti to the Hf₆₂Al₁₀Ni₈Cu₂₀ alloy is essential for the formation of I-phase. Retardation of the precipitation of FCC-Hf₂Ni in Hf₆₂Al₁₀Ni₈Cu₂₀ is considered as one of the reasons for the formation of I-phase caused by the addition of Ti. This effect is explained by considering the size mismatch between the constitute elements.
