Continuous preparation equipment and process for metal glass cladded metal wire composite material

Abstract

The invention discloses an equipment and process for continuously preparing metallic glass-coated metal wire composite materials by means of a melt impregnation method, belonging to the field of amorphous alloys (metallic glass). The invention is composed of a vacuum system, a heating system, a cooling device and a traction mechanism. Its technological features are as follows: the alloy prepared according to the nominal composition is smelted into a uniform master alloy in an electric arc furnace, and then the master alloy and metal wire are installed at the bottom In the crucible with a small hole, one end of the wire passes through the small hole of the crucible from the inside to the outside, remelts the master alloy in the heating furnace and keeps it warm, and then pulls down the metal wire immersed in the melt through the traction mechanism driven by the motor, so that Its surface is evenly impregnated with a layer of alloy liquid, and after passing through the heating zone, it is rapidly cooled by the cooling medium to form metallic glass, and finally obtain a metallic glass-coated wire composite material with high strength and elongation, which is suitable for use as body armor. Anti-collision helmets and other uses.

Description

Technical field: [0001] The invention belongs to the field of amorphous alloys, and in particular relates to continuous preparation equipment and technology for metallic glass-coated metal wire composite materials. Background technique: [0002] 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. [0003] 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 because of its unique properties that bulk metallic glasses have been more and more widely used in sporting go...

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, PP1632), however, affected by the glass-forming ability of metallic glass alloys, this method can only prepare samples of small size and simple shape (rod and plate), which greatly limits the Application range of materials
