Abstract

The invention relates to an amorphous alloy brazing method. A first amorphous alloy and a second amorphous alloy are aligned and fixed, it is guaranteed that a uniform gap exists between the two amorphous alloys, then a welding area is heated to a supercooled liquid phase area through an induction heating system, then stirring is conducted in the uniform gap through an amorphous alloy stirring needle till a welding head appears, and brazing of the amorphous alloy is completed. According to the scheme, the welding area is heated and maintained in the supercooled liquid phase area, crystallization of the amorphous alloy is avoided, the superplasticity of the amorphous alloy is fully utilized, and the brazing difficulty is reduced; and meanwhile, the amorphous alloy stirring needle made of the same material as the amorphous alloy is used for brazing, so that the welding head can be prevented from being polluted by a material falling off due to abrasion of the heterogeneous stirring needle, the influence of high temperature generated by heat accumulation of the amorphous alloy stirring needle on the material performance in the stirring process can be avoided, and the consistency of the material performance at a welding seam is ensured, and therefore, the amorphous alloy has stable performance.

Description

technical field [0001] The present application relates to the technical field of brazing, in particular to an amorphous alloy brazing method and device. Background technique [0002] Amorphous alloy is solidified by ultra-rapid cooling. When the alloy is solidified, the atoms have no time to arrange and crystallize in an orderly manner. The obtained solid alloy has a long-range disordered structure. The grains and grain boundaries of the state alloy exist. Compared with common crystalline metal materials, amorphous alloy materials have more advantages in mechanical properties such as hardness and elastic modulus due to the disordered arrangement of internal atoms. Taking Vit1 amorphous alloy as an example, its hardness reaches HV520, and its elastic modulus reaches 93GPa, which is much higher than that of aluminum alloy and stainless steel. At the same time, amorphous alloys with simple components provide ideal research samples for scientists to explore the mysteries of am...
