Amorphous alloy product and method for manufacturing same

Abstract

The invention discloses an amorphous alloy product which comprises a matrix and a heteroplasmon. The matrix is made from amorphous alloy, and the heteroplasmon is made from a heterogeneous material. The matrix is connected with the heteroplasmon, and one part of the heteroplasmon is exposed outside the matrix. The heteroplasmon is hard and is suitable for machining. The invention further discloses a method for manufacturing the amorphous alloy product, comprising the following steps: putting the heteroplasmon which is in a preset shape, is suitable for machining and is made from the heterogeneous material into a mould, and positioning the heteroplasmon; heating the amorphous alloy to above the glass transition temperature thereof, and injecting the amorphous alloy into the mould so that the amorphous alloy is connected and compounded with the heteroplasmon, wherein one part of the heteroplasmon is exposed outside the amorphous alloy; and cooling at the preset cooling speed which is higher than the critical cooling speed of the amorphous alloy to obtain the amorphous alloy product. The machining cost of the amorphous alloy product disclosed by the embodiment of the invention can be greatly reduced, and the problems that the amorphous alloy is hard to process and the heteroplasmon is subjected to thermal deformation when being compounded with the amorphous alloy are solved. The amorphous alloy product has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of amorphous synthetic materials, and more specifically, the invention relates to an amorphous alloy product and a manufacturing method thereof. Background technique [0002] Amorphous alloys appeared in the 1960s. The initial amorphous alloys could only reach the micron level because of the critical size (the largest size of the amorphous alloy), which made it difficult to be practically applied. However, due to its excellent material properties, it was favored by scientists Extensive research and continuous development of amorphous alloys with large critical size and suitable for industrial production. The critical size gradually develops from micron level to millimeter level or even centimeter level. Usually, the critical cooling rate is lower than 500°C / s , Amorphous alloys with a critical size greater than 1mm are called bulk amorphous alloys, and the emergence of bulk amorphous alloys provides the poss...

Problems solved by technology

However, once the amorphous alloy is formed, it is difficult to carry out secondary forming and secondary processing due to its high hardness and metastable microstructure. Among them, the hardness of zirconium-based amorphous alloy and copper-based amorphous alloy can reach dimensional The hardness is more than 500MPa, and the hardness of iron-based amorphous alloy or nickel-based amorphous alloy is as high as 800MPa, or even more than 1000Mpa. Therefore, the physical and chemical properties of amorphous alloys increase the difficulty of manufacturing more complex amorphous parts. Flexibility in Amorphous Alloy Design and Applications Creates Trouble

[0004] In the existing patents, the composite connection method of amorphous alloy and other materials is disclosed, but the connection of amorphous alloy and other materials, especially the connection of heterogeneous parts with complex shapes, is due to the influence of thermal shock and the expansion coefficient of the two materials during the forming process. It is easy to cause the deformation of the heterogeneous parts, making it difficult to realize the accurate positioning of the structure in the heterogeneous parts in the whole part, and even cause the deformation of the heterogeneous parts structure
