Description
Technical Field
The application relates to the technical field of composite materials, in particular to a metal reinforced amorphous matrix composite material and a preparation method thereof.
Background
The amorphous alloy is a novel metal material obtained from a high-temperature melt through an ultra-fast cooling process, and the microstructure of the amorphous alloy is characterized by long-range disorder and short-range ordered arrangement due to the fact that the amorphous alloy is not cooled. Based on this unique amorphous atomic structure, amorphous alloys exhibit many excellent mechanical properties, such as high toughness, high strength, high elastic strain limit, and good wear resistance. Nowadays, due to the excellent mechanical properties, various amorphous alloy materials are widely applied to various fields, and have wide application prospects in aerospace, electronic information and precision instruments. However, the desire to use amorphous alloys as structural materials also requires overcoming a number of obstacles. For example, the problems of room temperature brittleness, strain softening and the like of amorphous alloys in the deformation process greatly restrict the practical application of the amorphous alloys as structural materials.
In the prior art, researchers propose adding a material capable of enhancing toughness to an amorphous alloy, so that the amorphous alloy has the advantages of high strength, high hardness and high wear resistance of the amorphous alloy and the advantage of high toughness of a tough material, and the novel material is called an amorphous matrix composite material. Various preparation methods have been proposed for amorphous-based composite materials, such as a pressure infiltration method and a stainless steel pipe water quenching method. The pressure infiltration method is to infiltrate the molten amorphous alloy melt into the wrapped material under a certain pressure condition, so that the interface combination condition of the amorphous alloy and the reinforcement can be effectively improved, the internal structure of the obtained composite material is compact, the problem of wrapping gas and inclusion can be avoided by controlling the melting process, and the method is a better method for preparing the amorphous composite material, however, the too slow cooling rate is one of the reasons for crystallizing the amorphous matrix. Meanwhile, the water quenching method of the stainless steel tube also has the problem of limited cooling speed, can directly influence the crystallization behavior of an amorphous base, and cannot ensure the forming size of the obtained composite material. At present, a plurality of problems are solved for preparing the amorphous-based composite material so as to be further applied, and the improvement of the preparation method is particularly important.
Many metal elements have excellent mechanical properties, so metals such as tungsten are commonly selected as reinforcing materials in the preparation of composite materials. The addition of a ductile phase, such as particles, fibers or filaments, to the amorphous matrix to enhance the toughness of the amorphous material is a reinforcing phase that is currently in common use. In particular, the metal reinforced amorphous matrix composite material has high strength, high hardness, wear resistance and other excellent properties, also has very excellent impact resistance and armor piercing performance, and has potential armor application prospect. The amorphous base alloy component selected by the application is Zr 61 Ti 2 Cu 25 Al 12 Amorphous alloys (of course, the application is also applicable to other amorphous alloys), and a great deal of research in the early stage proves that Zr 61 Ti 2 Cu 25 Al 12 The amorphous alloy component has excellent mechanical property and high fracture toughness. However, since there are a large number of voids in the resulting composite between the metal reinforcing phase material and the metal reinforcing phase material, between the metal reinforcing phase material and the amorphous matrix, this also affects the metal reinforcing non-crystalline matrixOne of the important factors of the mechanical properties of the crystal-based composite material.
Impact toughness refers to the ability of a material to absorb plastic deformation work and fracture work under impact load, reflects fine defects and impact resistance inside the material, and reflects the resistance of a metal material to external impact load. Materials with high impact toughness are often used in engineering construction, aerospace, military industry and other fields. Because the amorphous alloy has excellent mechanical properties, a novel amorphous-based composite material is prepared by taking a high-strength metal reinforced phase material as a reinforced material, and the application prospect of the amorphous-based composite material in the aspect of impact toughness can be searched.
In summary, the existing preparation methods of metal reinforced amorphous-based composite materials still face the problems of easy crystallization of amorphous-based alloy materials, introduction of gaps and holes, etc., and the key to solve these problems is to find a new preparation method or to improve the existing process.
