Abstract

The invention relates to a zirconium base amorphous composite material, containing a main material shown as the general formula: [(Zr1-xHfx)52Al10Cu30.5(Ni1-yFey)7.5)100-a-bYaMb, wherein x is the ratio of the atomic number of Hf to the total atomic number of Hf and Zr, and x ranges from 0 to 0.3; y is the ratio of the atomic number of Fe to the total atomic number of Fe and Ni, and y ranges from 0 to 0.3; a is the atomic percentage of Y, b is the atomic percentage of M, a is more than 0 and less than or equal to 8, and b is more than or equal to 0.01 and less than or equal to 15; M is one or more of La series metal elements, Ti, V, Nb, Ta, Cr, Mo, W, Mn and Si; and by taking the total volume of the zirconium base amorphous composite material as a reference, the content of an amorphous phase in the amorphous composite material is 50-95%, and the content of a crystalline phase is 5-50%. The zirconium base amorphous composite material provided by the invention has good comprehensive performance..

Description

technical field [0001] The present invention relates to an amorphous composite material and a preparation method thereof, more specifically, the present invention relates to a zirconium-based amorphous composite material and a preparation method thereof. Background technique [0002] Amorphous alloys are a new class of alloy materials whose constituent atoms are long-range disordered and short-range ordered. Due to its unique microstructure, it has superior mechanical, physical and chemical properties than conventional crystalline metal materials. These superior properties make amorphous alloys have potential applications in many fields. [0003] Since the early 1990s, led by Japan and the United States, a series of alloy components with strong amorphous forming ability have been discovered, among which zirconium-based amorphous alloys are the easiest to prepare, and their critical cooling rate is 1K / s It can be prepared into three-dimensional block materials by methods su...
