Problems solved by technology

Although the above schemes all propose the application of amorphous alloy as a specific tool, the main solution in the scheme is the lack of strength and scratch resistance of the tool material used in a specific environment. The amorphous alloy material can only be used as a tool. Razors or ice skates are not used as "knives" in a broad sense

Embodiment 1

[0046] The preparation method of amorphous alloy cutter in the present embodiment is:

[0047] Separately set up the whole tool mold and the blade part mold. The overall mold of the tool is designed according to the overall contour of the tool, and the mold of the blade part is designed according to the requirements of the blade part during processing.

[0048] The first choice is to process the amorphous alloy raw material (the raw material composition is Zr42.7Ti12.3Cu22.4Ni11.6Al11) into the overall shape of the tool by vacuum die-casting. rate of 10 3 -10 4 K / s, the clamping force is 1.3-1.5 times of the supporting force; the proportion of amorphous state in the prepared amorphous alloy tool is about 89% (calculated by microscope observation).

[0049] Then, heat the blade part until it is softened, and the softened state is a state that can be pressed and formed, but it has not yet reached the glass transition temperature, and then the blade part is placed in the blade...

Embodiment 2

[0052] The preparation method of the amorphous alloy cutting tool in this example is almost the same as that in Example 1, except that the raw material composition of the amorphous alloy used is Ti48.7Zr17.5Ni16.9Be16.9, and the melting temperature is 1010-1020°C , the proportion of amorphous state in the prepared amorphous alloy cutting tool is about 92% (calculated by microscope observation).

Embodiment 3

[0054] The preparation method of the amorphous alloy cutting tool in this example is almost the same as that in Example 1, the difference is that the raw material composition of the amorphous alloy used is Fe46.7Co24Cr11Mo3B6.7Y5Mn2.6N0.6C0.4, and the melting temperature is 1010- At 1020°C, the proportion of amorphous state in the prepared amorphous alloy cutting tool is about 85.3% (calculated by microscope observation).

Abstract

The invention discloses a low-wound amorphous alloy cutter. A cutting edge of the cutter is made of amorphous alloy. The amorphous alloy comprises one or more of zirconium-based amorphous alloy, copper-based amorphous alloy, aluminum-based amorphous alloy, iron-based amorphous alloy, tantalum-based amorphous alloy, titanium-based amorphous alloy, cobalt-based amorphous alloy, nickel-based amorphous alloy and rare-earth-based amorphous alloy, and the ratio of amorphous states in the amorphous alloy is larger than equal to 85%. The invention provides the amorphous alloy cutter with the cutting low wound and a preparation method of the cutter. A blade of the amorphous alloy cutter is high in hardness and sharpness, the whole cutter has high yield strength and low surface energy, wounds at cutting positions are small in the cutting process, the cutting smoothness is high, and the cutting efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the application field of amorphous alloy materials, and in particular relates to a low-wound amorphous alloy cutting tool and a preparation method thereof. Background technique [0002] Cutting tools are tools used for cutting in the industrial field. Most of the knives are made of metal materials, such as the most widely used stainless steel knives in the industrial field. The material used to prepare knives must have good high-temperature hardness and wear resistance, as well as flexural strength and impact toughness that meet the requirements of use. High-speed steel is a modern industry due to its high flexural strength, impact toughness and good machinability. The most commonly used cutting tool material, followed by various types of cemented carbide. With the gradual development of the material industry, cutting tools of various materials emerge in an endless stream, such as polycrystalline cubic boron nitride materials...
