Abstract
Abstract Novel metal alloy compositions which are obtained in the amorphous state and are superior to such previously known alloys based on the same metals are provided; these new compositions are easily quenched to the amorphous state and possess desirable physical properties. Also disclosed is a novel article of manufacture in the form of wire of these novel amorphous metal alloys and of other compositions of the same type.
