Abstract

An experimental study of a multicomponent bulk metallic glasses (BMG) alloy, Zr_52.5Cu_17.9Ni_14.6Al₁₀Ti ₅, utilizing several characterization techniques was reported. The study used an atom-probe equipped with a high-repetition pulsed laser, together in situ with SAXS. The BMG samples were prepared by a drop-casting method, with glass and crystallization temperature as 628 and 714K, determined by differential scanning calorimetry. SAXS experiments were performed using the high-energy synchrotron beam at sector 1-ID at Advanced Photon Source (APS), Argonne National Laboratory. The results have important implications in understanding the mechanisms of nucleation and growth of nanocrystalline precipitates and the stability of BMG alloys. nucleation of Zr₂(Ni, Cu) core also results in Al expulsion into the region surrounding the core, forming a shell. This combination helps to stabilize the composite structure with nanocrystalline precipitates distributed in glassy matrix.
