Research Status and Development Trend of Cu-Zr- Based Amorphous Alloys

“…Since Au-Si [1] amorphous alloy was prepared in the United States in the 1960s, the researchers found that the amorphous alloy has a special structure and more some excellent properties such as high strength, hardness and fracture toughness, compared to crystalline materials, so it was considered as a new material with significant application potential, furthermore, amorphous alloys had become a new focus of domestic and foreign in material research field since the 1980s [2][3] . Because the Cu-based amorphous alloy holds a relatively low price with a widely application in the engineering field and the Zr-based amorphous alloy possess a higher strength, elastic modulus, hardness and so on, their preparation technologies and properties had been further improved by the researcher in recent ten years [4][5][6] . Therefore, the Cu-Zr-based amorphous alloys have been received a special attention and is a focus of research in the field of amorphous alloys.…”
