Abstract
The model we have previously used to predict the glass-forming range of binary transition-metal alloys is extended to ternary systems. As in the binary case, the treatment combines classical elasticity theory and Miedema's model for the heat of formation of alloys, and takes into account the factors which are recognized as most influencing glass formation, specifically the valency, the electro-negativity and the atomie size mismatch. As an application of the theory, we study the amorphization of the Cu–Ti–Zr system and its associated binary systems, for which the influence of working conditions on the glass-forming range is examined.
