Abstract

The invention relates to a tungsten-base amorphous alloy which is characterized in that the chemical composition of the tungsten-base amorphous alloy calculated by atom fraction comprise: 30 percent to 40 percent of W, 10 percent to 30 percent of Fe, 10 percent of 30 percent of C, 0 percent to 10 percent of Si, 0 percent to 10 percent of Ni, 0 percent to 15 percent of Cr, 0 percent to 10 percent of Mn, 0 percent to 10 percent of Mo, 0 percent to 10 percent of Co, 0 percent to 2 percent of Y, 0 percent to 2 percent of Sc, 0 percent to 2 percent of Er and 0 percent to 2 percent of Gd; the thickness of an amorphous alloy strap is 25Mum to 40Mum; and crystallization temperature is 900K to 1100K. The tungsten-base amorphous alloy of the invention has the advantages of high crystallization temperature, and good thermal stability of amorphous alloy, high stiffness, good abrasive resistance and comparatively low cost, etc.

Description

technical field [0001] The invention relates to an amorphous metal material with metal tungsten as a matrix, and belongs to the technical field of tungsten-based alloy metastable materials and preparation. Background technique [0002] Since Duwez first prepared the Au-Si amorphous alloy by melt quenching technology in 1960, the amorphous alloy has become a hot spot pursued by many researchers because of its unique structure and properties. For decades, through the efforts of researchers and breakthroughs in the optimization design of alloy system components, people have obtained amorphous state in many alloy systems such as: Zr-based, Ti-based, Ni-based, Cu-based, Pd-based, etc. Alloy structures, even bulk amorphous alloys. Amorphous alloys have been widely used for their high strength, high elastic modulus, good corrosion resistance and oxidation resistance, and high wear resistance. In order to meet the requirements of different working conditions, amorphous alloys with...
