Structure and Crystallization of Cu<SUB>50</SUB>Ti<SUB>50−<I>x</I></SUB>Al<I><SUB>x</SUB></I> Amorphous Alloys

Abstract

In the Cu 50 Ti 50-x Al x system, amorphous alloys are obtained by melt-quenching technique in the range O≤x≤40. The structure of these glasses is investigated by X-ray radial distribution function (RDF) analysis, and the crystallization behavior is studied by differential scanning calorimetry and X-ray diffraction. A Cu-Cu pair correlation is resolved in the differential reduced RDF, ΔG(r), which has been obtained by subtracting G(r) for binary Cu 50 Ti 50 from those for ternary alloy glasses. The radial distances for the correlation peaks are consistent with those for a dense random packing
