Embodiment 1

[0038] This embodiment is a processing method for removing flash of an amorphous alloy ball. During the processing, a self-made tool system is used to rub the amorphous ball at high speed, such as image 3 As shown, the self-made tool system includes a cylindrical fixed body and a cylindrical cutter, and one end of the cylindrical fixed body is set as a hemispherical concave structure, and the hemispherical concave structure is compatible with the amorphous alloy ball to be processed. Size fits. One end of the cylindrical tool is an annular blade-shaped structure, and the amorphous alloy ball to be processed is fixed through the cooperation of the hemispherical concave structure and the annular blade-shaped structure. After the amorphous alloy ball is fixed, the annular blade of the tool is closely attached to the inner edge of the flash of the amorphous alloy ball. The cylindrical fixed body can be rotated through the control of the machine tool, and can also be fixed. The ...

Abstract

The invention discloses a processing method of an amorphous alloy member, and belongs to the technical field of amorphous alloy processing. The processing method comprises the following steps that theglass-transition temperature and the crystallization initial temperature of amorphous alloy under continuous heating conditions are measured; the crystallization starting time of the amorphous alloyunder the isothermal condition is measured; and the amorphous alloy is subjected to friction heat generation processing - rapid cooling, and amorphous alloy products are obtained. According to the processing method of the amorphous alloy member, the characteristic that the viscous resistance of the amorphous alloy is reduced in an overcooling liquid phase region is utilized to process the amorphous alloy, the problems that the amorphous alloy is difficult to machine at room temperature, long in processing period, high in cost and the like are solved, and feasibility is provided for the processing and application of the amorphous alloy.

Description

technical field [0001] The invention relates to the technical field of amorphous alloy processing, in particular to a processing method of an amorphous alloy component. Background technique [0002] Amorphous alloy, also called metallic glass, is usually prepared by rapid solidification of liquid alloy melt, and its internal structure is a long-range disordered amorphous structure similar to glass. The unique atomic arrangement structure of amorphous alloy makes it have many excellent characteristics, the most notable of which is its high strength and hardness. At the same time, amorphous alloy usually behaves as a brittle material and hardly exhibits tensile plasticity. These characteristics make the processing of amorphous alloys extremely difficult. It is difficult to process them using conventional machining tools and processes, and it is even more difficult to guarantee the processing accuracy. Therefore, it is necessary to explore low-cost, fast and efficient amorphou...
