Abstract

The invention discloses a Si element contained Ti-based amorphous alloy. The Si element contained Ti-based amorphous alloy is characterized in that the amorphous alloy comprises five components including Ti, Cu, Zr, Ni and Si, and the chemical component is (TiaCubZrcNid)1-eSie, wherein 45at.%<=a<=55at.%, 14at.%<=b<=20at.%, 15at.%<=c<=27at.%, 10at.%<=d<=13at.%, 0at.%<e<=2at.%, and a+b+c+d=100%. According to the Si element contained Ti-based amorphous alloy, the Si element is selected as an alloy component, and the amorphous forming ability of the Ti-Cu-Zr-Ni alloy is improved. In addition, theelements including the Cu and the Ni are added, and therefore the melting point of Ti-based amorphous brazing filler metal can be reduced, the wetting spreadability of the brazing filler metal is better improved, and the Ni and the Zr can improve the stability performance of subcooled liquid and the possibility of amorphous formation.

Description

technical field [0001] The invention relates to a Ti-based amorphous alloy containing Si element and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] In 1938, Kramer used evaporation deposition technology to prepare amorphous metal thin film for the first time, which should be the earliest amorphous alloy prepared. In 1950, American physicist Turnbull directly prepared amorphous metals using mercury supercooling experiments, and proposed some empirical principles for the formation of amorphous alloys: large size difference, large negative heat of mixing, low eutectic point, constituent atoms Asymmetric Diffusion etc. In 1978, Decristofaro et al. reported the amorphous solder alloy for the first time, introducing that the amorphous solder has the advantages of uniform chemical composition, which can reduce the addition of precious metals in the solder. Amorphous alloy is a new type of metal material prepared by l...
