Abstract

This paper reports the crystallization process of Zr₆₀Ni₂₅Al₁₅ amorphous alloy studied by using differential scanning calorimetry (DSC), analytical transmission electron microscopy (ATEM) and X-ray diffraction (XRD). The crystallization of Zr₆₀Ni₂₅Al₁₅ amorphous alloy proceeds through an eutectic reaction, corresponding to the precipitation of Zr₆NiAl₂ and Zr₅Ni₄Al phases. The following reasons are addressed to the large glass-forming ability (GFA) of Zr₆₀Ni₂₅Al₁₅: (a) the significant atomic redistribution of Al and Ni in the dense random packed atomic configuration and (b) the strict elemental limitation for a determined crystal site in the precipitation of Zr₆NiAl₂ and Zr₅Ni₄Al.
