FABRICATING METHOD FOR NITRIDE REINFORCED BULK METALLIC GLASS MATRIX COMPOSITE MATERIAL AND COMPOSITE MATERIAL FABRICATED BY THE METHOD

摘要

The present invention relates to a method for producing an amorphous alloy-base composite material reinforced with nitride, comprising the steps of: preparing a raw material containing AlN as a nitrogen source for supplying nitrogen and at least one element selected from Zr and Ti as a nitride- Preparing; Melting the raw material to form a molten metal; And quenching the molten metal to form an amorphous alloy base, wherein the nitrogen of the AlN in the molten metal binds with the nitride-forming element to form a nitride spontaneously. The present invention has the effect of producing an amorphous alloy matrix composite in which nitrides are dispersed without additional steps of mixing the nitride by spontaneously forming the nitride in the molten metal. Further, since the nitride spontaneously formed in the molten metal is dispersed, the nitride is highly dispersed and has excellent interfacial characteristics between the matrix and the nitride phase. Further, the composite material produced by the present invention has an effect of providing an amorphous matrix composite material having high elasticity, high strength and high elongation by dispersing nitride in an amorphous alloy base.
