Abstract
Abstract A composite material composed of a matrix and an amorphous material of a desired disposition state is produced by positioning a given shape of crystals, of a type easily transformable to the amorphous state by irradiation with a particle ray, on the surface and/or the interior of the matrix, at a predetermined position, and irradiating the crystals by the particle ray under an irradiation condition for transforming the crystals preferentially to the amorphous state.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
92 words
A method of producing a composite material composed of a matrix and an amorphous material, characterised in that it includes the steps of positioning a given shape of crystals, of a type easily transformable to the amorphous state by irradiation with a particle ray, at a desired position on the surface and/or the interior of the matrix, and irradiating the crystals by the particle ray under an irradiation condition for transforming the crystals preferentially to the amorphous state, whereby a composite material with a desired disposition state of amorphous phase is obtained.
Claim 2
Independent Claim
92 words
A method of producing a composite material composed of a matrix and an amorphous material, characterised in that it includes the steps of positioning a given shape of crystals, of a type easily transformable to the amorphous state by irradiation with a particle ray, at a desired position on the surface and/or the interior of the matrix, and irradiating the crystals by the particle ray under an irradiation condition for transforming the crystals preferentially to the amorphous state, whereby a composite material with a desired disposition state of amorphous phase is obtained.
Claim 3
Dependent Claim
54 words
A method according to claim 1, wherein the crystals of the type easily transformable to the amorphous state by irradiation with a particle ray are of an intermetallic compound such as Zr 2 Al, Fe 2 Ti, ZrCu, U 3 Si, Cu 3 Ti, NiTi, CoTi, Cu 3 Ti 2 and/or iron-zirconium series compounds.
Claim 4
Dependent Claim
17 words
A method according to claim 1 or claim 2, wherein the particle ray utilised is electron beam.
Claim 5
Independent Claim
40 words
A method according to any one of claims 1 to 3, wherein the product after irradiation by the particle ray is, as a whole, subjected to diffusion annealing at a temperature immediately below the crystalliation temperature of the amorphous phase.
Claim 6
Independent Claim
65 words
A method according to any one of claims 1 to 3, wherein the product after irradiation with the particle ray is, as a whole, subjected to an annealing treatment at a temperature at least slightly higher, than the crystallization temperature of the amorphous phase to produce a crystalline phase, and thereafter irradiated again by a particle ray to transform the crystalline phase to amorphous state.
