Abstract

The present invention discloses a titanium-based amorphous fiber and a preparation method thereof, and solves the problem that reaction of quartz crucible in the preparation of Ti-based amorphous fiber without Be can result in failure of Ti-based fiber preparation in the prior art. A general chemical formula of the titanium-based amorphous fiber is as below: Ti(58-x)Zr(20+x1)Cu(8+x2)Ni(9+x3), wherein x, x1, x2 and x3 satisfy the relations of: 0<=x<=8,0<=x1<=10,0<=x2<=5,0<=x3<=3, and the sum of 58-x, 20+x1, 8+x2, 9+x3 is 100. The preparation method: in protective gas or vacuum conditions, conducting laser heating on Ti-based amorphous alloy to form partially molten alloy, and continuously feeding; cutting the alloy melt by a metal wheel, drawing and rapidly cooling to form the Ti-based amorphous fibers. The above method overcomes the problems of shaping difficulty of Be-free titanium-based amorphous fibers, and failure of Ti-based fiber preparation due to reaction of the titanium-based amorphous alloy with the quartz crucible. The prepared titanium-based amorphous fiber has good thermal stability and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a titanium-based amorphous fiber and a preparation method thereof. Background technique [0002] Amorphous alloys have a liquid-like structure and there are no defects such as dislocations and grain boundaries in the crystal, which makes amorphous alloys have some excellent mechanical properties. Such as high strength, high hardness, high elastic strain and other characteristics, amorphous alloys can also be cast as easily as plastics, and this excellent performance and forming ability make it possible to replace some traditional materials. Ti-based amorphous alloys have gradually attracted the attention of scholars from various countries due to their high specific strength and low price. Among them, titanium-zirconium-nickel-copper-beryllium (Ti-Zr-Ni-Cu-Be) alloys have The higher amorphous forming ability has attracted much attention, but Be in the system is a hig...
