Continuous preparation equipment and process for fiber-reinforced metal glass composite filament

Abstract

The invention provides continuous preparation equipment and a process for a fiber-reinforced metal glass composite filament, and belongs to the field of amorphous alloy (metallic glass). The continuous preparation equipment is composed of a vacuum system, a pay-off wheel set, a heating system, a cooling device and a dragging mechanism. A heating carrier is placed in the high vacuum system so as to obtain a composite interface with good bonding property, no blends and complete cleaning performance. By adopting the method for paying off, a double-guide-wheel device is used, the two guide wheels are tangent in the two guide wheels, and the lower guide wheel is connected with a motor so as to directly wind the prepared filament, thus realizing the continuous and large-scale production and achieving the purposes of short procedures and energy conservation and consumption reduction. The continuous preparation equipment and process are applied to preparation of armour piercing materials and other uses.

Description

[0001] technical field [0002] The invention belongs to the field of amorphous alloys, and in particular relates to continuous preparation equipment and technology for fiber-reinforced metallic glass composite material filaments. Background technique [0003] Metallic glass (also known as amorphous alloy) refers to a metal alloy that has short-range order and long-range disorder in the arrangement of atoms in the solid state, and maintains this state relatively stable within a certain temperature range. In the past ten years, the development of bulk metallic glass is a milestone in its development process, making it possible for metallic glass to be used as a structural material. [0004] Compared with traditional crystal materials, bulk metallic glasses have outstanding advantages such as higher strength (~2GPa), large elastic limit (2%~3%), and good corrosion resistance. It is precisely because of its unique properties that bulk metallic glasses have been more and more w...

Problems solved by technology

At present, the main method of preparing tungsten wire reinforced bulk metallic glass composites is percolation casting method (document 4, Wang Meiling, Hui Xidong, Dong Wei, Liu Xiongjun, Chen Guoliang. Tungsten wire reinforced ZrTiCuNiBeNb metallic glass matrix composite interface. Chinese Journal of Nonferrous Metals , Vol.14, 2004, P1632, Document 5, Zhang Xingchao, Chen Xiaohua, Zhang Yong. Ultra-high strength and plasticity tungsten wire reinforced ZrTiCuNiBeNb metallic glass composite rare metal materials and engineering, 2008, 37 (Supplement 4): 786-789 ), however, one of the biggest disadvantages of the infiltration casting method is that the contact time between the fiber and the alloy liquid is long. Therefore, an interface reaction occurs between the fiber and the melt or between the fiber and the solidified high-temperature matrix, and the effect of the reinforcement is reduced.
