Embodiment 1

[0045] This example provides a high-entropy five-element metal carbide solid solution, including a first metal element carbide and a second metal element carbide, the first metal element carbide includes three carbides of TiC, TaC and NbC, so The second metal element carbides include WC, ZrC, VC, Mo 2 Any two carbides in C and HfC.

[0046] The performance of the high-entropy five-element metal carbide solid solution is stable, and it is a single-phase solid solution powder material.

Embodiment 2

[0048] This example provides the preparation process of high-entropy quinary metal carbide solid solution, the steps include:

[0049] S1: Weigh the oxide powder of the first metal element, the carbide powder of the second metal element and carbon black according to the proportion, mix and ball mill and sieve;

[0050] S2: Carrying out carbonization and reduction treatment on the product obtained in step S1 in a reducing atmosphere to obtain the high-entropy five-membered metal carbide solid solution.

[0051] The preparation process has simple steps, does not require complex equipment, the preparation conditions are not harsh, and the production cost is low;

[0052] In the preparation process, the raw material used is the oxide powder of the first metal element instead of directly using the first metal element, which effectively reduces the manufacturing cost.

[0053] Wherein, the particle size of the oxide powder of the first metal element and the carbide powder of the se...

Abstract

The embodiment of the invention provides a high-entropy five-membered metal carbide solid solution and a preparation process thereof. The high-entropy five-membered metal carbide solid solution has stable performance and is a single-phase solid solution powder material. The preparation process steps are simple and complicated equipment is not needed. Preparation conditions are not harsh, and production cost is low. In a preparation process, the adopted raw material is oxide powder of a first metal element, and direct adoption of the first metal element is avoided, so that manufacturing cost iseffectively reduced.

Description

technical field [0001] The invention belongs to the technical field of hard alloys, and in particular relates to a high-entropy five-element metal carbide solid solution and a preparation process. Background technique [0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. The performance, especially its high hardness and wear resistance, can basically remain unchanged even at a temperature of 500°C, and it still has a high hardness at 1000°C. [0003] Cemented carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for Cutting heat-resistant steel, sta...
