Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
103 words
A composite alloy produced by rapid quenching comprising a matrix composed of a rapidly quenched amorphous alloy, and particles of a second phase substance having a melting temperature higher than that of the matrix, which particles are coercively and uniformly three-dimensionally dispersed in the matrix without the formation of pores after rapid quenching, wherein the second phase substance is NbN powder which has a face centered cubic lattice structure at ordinary room temperature and is approximately 20% by volume of the composite alloy, and said matrix is an amorphous Zr--Nb--Si alloy having superconductive properties and a high critical temperature of about 12 K.
