Problems solved by technology

In the prior art, the diaphragms of flexible couplings are mostly made of stainless steel. Although stainless steel diaphragms are stronger and more wear-resistant than the early carbon steel diaphragms, in some high-precision, high-speed, special-demand occasions Still can not meet customer requirements

Abstract

The invention discloses a preparation method and application of a toughened amorphous alloy material in a cryogenic cycle combined pre-deformation mode, and belongs to the technical field of amorphous alloy applications. The flexible coupling diaphragm of the toughened amorphous alloy is processed by the combination of cryogenic cycle and pre-deformation. It is melted in a vacuum electric arc furnace, and the water-cooled copper mold is quickly suction-cast into a plate-shaped amorphous alloy. The cryogenic cycle is treated and 5% rolling After pre-deformation, rough and finish machining into the required diaphragm. The toughened amorphous alloy diaphragm treated by the combination of cryogenic cycle and pre-deformation in the present invention has the advantages of high elastic limit (2%), high hardness, high strength, wear resistance, long service life and the like. The diaphragm of the flexible coupling is made of Zr-based amorphous, which broadens the application of the flexible coupling in high-end, precision, and special-demand occasions, and has high commercial use value.

Description

technical field [0001] The invention relates to a preparation method and application of a toughened amorphous alloy material in a cryogenic cycle combined pre-deformation mode, and belongs to the technical field of preparation and application of amorphous alloys. Background technique [0002] Amorphous alloys have many excellent properties due to their unique structural characteristics such as long-range disorder, short-range order, and no grain boundaries, such as large elastic limit (elastic limit 2%), high fracture strength, high hardness, good Excellent corrosion resistance and friction resistance, it is a structural material with broad application prospects. These unique properties provide excellent elastic behavior, which is rarely seen in crystalline metals. However, the plastic deformation of amorphous alloys at room temperature is limited to shear bands on the order of 10 nm, and amorphous alloys exhibit brittle fracture due to the rapid expansion of a single shear...
