Problems solved by technology

In the prior art, the diaphragm of the flexible coupling is usually made of stainless steel. Although the strength of the stainless steel diaphragm is higher than that of the early carbon steel diaphragm, and it is more wear-resistant, the stainless steel diaphragm still has elastic limit, strength, Disadvantages of poor hardness, wear resistance and corrosion resistance
In some occasions with high precision, high speed and special requirements, it still cannot meet the requirements

Abstract

The invention discloses an amorphous composite and a method for preparing a flexible coupling diaphragm by using the amorphous composite, and belongs to the technical field of application of amorphouscomposites. The flexible coupling diaphragm is made of a Ti-based amorphous composite or a Zr-based amorphous composite. According to the flexible coupling diaphragm made of the amorphous composite,an amorphous composite master ingot is smelted by using a vacuum arc furnace, a plate-shaped amorphous composite is subjected to suction casting by using a copper mold, heat treatment is performed before and after rolling, two-dimensional high-temperature rolling and room-temperature rolling for pre-deformation are performed, rough and finish machining is performed, and the diaphragm with the required size is obtained. The flexible coupling diaphragm made of the amorphous composite has the advantages of high elasticity (the elastic limit is 1.5%-1.7%), high strength, high toughness, high hardness, excellent corrosion resistance, fatigue resistance, long service life and the like.

Description

Technical field [0001] The invention relates to an amorphous composite material and a method for preparing a flexible coupling diaphragm, and belongs to the technical field of application of amorphous composite materials. Background technique [0002] Due to the unique long-range disorder and short-range order of atomic arrangement, amorphous alloys have some excellent properties that crystalline alloys cannot match, such as high elastic limit, hardness, strength, excellent wear resistance, corrosion resistance and fatigue resistance. However, due to the lack of deformation mechanisms such as dislocations, twins, and phase transitions in crystalline alloys, the deformation of room temperature amorphous alloys can only rely on the initiation and expansion of local shear bands, and room temperature amorphous alloys exhibit brittle fracture. The emergence of amorphous composite materials timely solved the problem of room temperature brittle fracture of amorphous alloys on the engine...
