Correlation between reduced glass transition temperature and glass forming ability of bulk metallic glasses

Abstract

In this study, onset temperature (solidus), Tm and offset temperature (liquidus) Tl of melting of a series of bulk glass forming alloys based on Zr, La, Mg, Pd and rare-earth elements were measured by studying systematically the melting behavior of the alloys using DTA or DSC. The significance of Trg based on Tg/Tm or TgTl and the correlation between resulting Trg and glass forming ability of the bulk glass forming alloy was determined.
