Abstract
In order to predict the glass forming ability of binary alloys produced by ion beam mixing, a two dimensional map is constructed. The two coordinates of this map are the ratio of atomic radii r A / r B , and the heat of formation Δ H of an equiatomic compound, calculated using Miedema's model. In this map, binary systems which form in the amorphous phase are clearly separated from the others. The same map is valid both for metal-metal and metal-semiconductor binaries.
