Method of producing a composite material composed of a matrix and an amorphous material

摘要

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 an 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 of transforming the crystals preferentially to the amorphous state.
