AMORPHOUS COMPOSITE MATERIAL HAVING IMPROVED TENSILE AND ELONGATION CHARACTERISTICS AT ROOM TEMPERATURE AND METHOD FOR PREPARING SAME

摘要

The present invention has been devised to solve the problems of conventional amorphous alloys, wherein the aim of the invention is to provide a novel amorphous composite material having improved tensile characteristics which are weak in conventional amorphous alloys, while maintaining the high strength, hardness, corrosion resistance, etc. of amorphous alloys. To accomplish the aim, the amorphous composite material of the present invention comprises 45 to 50 atom % of Ti, 22 to 30 atom % of Zr, 4.5 to 7 atom % of Ni, 10 to 20 atom % of Be, and 5 to 9 atom % of Nb, the remainder being unavoidable impurities, and partially comprises a crystalline phase.
