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.
Claims8
A metal alloy composed of Fe.sub.d Ni.sub.e P.sub.f B.sub.g C.sub.h which is at least 50% amorphous, wherein d, e, f, g and h represent atomic percentages in the range of from 15 to 55, 30 to 70, 10 to 20, 1 to 10 and 0 to 5, respectively, f plus g plus h ranges from 15 to 25, and the total of the atomic percentages equals 100.
