Abstract

It has been confirmed that glass-forming ability (GFA) is related to not only liquid phase stability but also the crystallization resistance. In this study, it was found the liquidus temperature Tl and supercooled liquid region Tx - Tg could reflect the stability of glass-forming liquids at the equilibrium and undercooled state, respectively, while the onset crystallization temperature Tx could indicate the crystallization resistance during glass formation. Thus, a modified γ parameter, defined as γm = (2 Tx - Tg) Tl, has been established. This parameter shows an excellent correlation with the GFA of bulk metallic glasses, with the statistical correlation factor of R2 =0.931. © 2007 American Institute of Physics.
