Patent ID: 8906172

Claim:
An amorphous alloy composite material comprising a matrix phase and a reinforcing phase, wherein: the matrix phase is a continuous and amorphous phase; the reinforcing phase comprises a plurality of equiaxed crystalline phases dispersed in the matrix phase; and the amorphous alloy composite material has an oxygen content of less than about 2100 ppm, wherein the amorphous alloy composite material has a composition represented by the general formula of ((Zr 1-a Hf a ) b Ti c Cu d Ni e Be f ) 100-x Nb x where: a is an atomic weight ratio of Hf to a total atomic weight of Zr and Hf, wherein 0.01<a<0.1; b, c, d, e, and f are atomic weight ratios, wherein 50<b<65, 10<c<20, 2<d<10, 1<e<10, and 4<f<20, and b+c+d+e+f=100; and x is the atomic weight ratio of Nb, wherein 0<x<10.
