Abstract
The atomic size effect on the glass formability of rapidly solidified metallic materials is explored by using the atomic volume mismatch estimated from the cube of the atomic radius of solvent and solute. The product of the atomic volume mismatch and the minimum solute concentration required to obtain a stable glassy phase is empirically found to be a nearly constant value of 0.10 in various binary alloys and some ternary alloys known as glass forming systems. On the basis of such empirical correlation, the optimum solute concentration for good glass formability is discussed at the phenomenological level, using the results of Fe-Si-B-Cr quarternary alloys as an example.
