Abstract

This paper summarizes our recent work on the understanding of glass formation from considering both liquid phase stability and crystallization resistance from a physical metallurgical point of view. A comprehensive expression to predict glass-forming ability (GFA) for various glass-forming systems, γ=Tx/(Tg+Tl), was derived, where Tx is the crystallization temperature, Tg the glass transition temperature and Tl the liquidus temperature. Our physical-metallurgy approach is supported strongly by experimental data reported for various bulk amorphous materials. Also, some misconception commonly used for assessing the GFA in the literature will be clarified. © 2004 Elsevier Ltd. All rights reserved.
