Problems solved by technology

After thermal processing and heat treatment, M 2 C→M 6 C+MC, M 2 C decomposition can refine carbides, but M 2 C often has insufficient decomposition, and the remaining amount is 1.0 to 3.0%. It is usually called rod-shaped carbide, and this rod-shaped M 2 The existence of C eutectic carbide not only affects the hot working performance of high speed steel, but also affects the service life of cutting tools
These factors hinder the application and development of high-speed steel W2Mo9Cr4VCo8

Embodiment 1

[0017] A high-speed steel, said high-speed steel comprises the following components by mass percentage:

[0018]

[0019] The sum of the above chemical components is 100%.

[0020] The above-mentioned high-speed steel is prepared by smelting-diffusion annealing-hot processing-cold drawing.

[0021] The thermal processing includes precision forging machine forging process and rolling process. The forging process of the precision forging machine is as follows: the furnace temperature is 600°C; the temperature is raised from 600°C to 900°C for preheating, and the heating rate is 2°C / min; the temperature is raised from 900°C to 1040°C, and the heating rate is 1°C / min; Heat preservation at 1090°C, the heating rate is 1°C / min; the final forging temperature is 900°C, and annealed after forging. The rolling process is as follows: the furnace temperature is 700°C; the temperature is raised from 700°C to 900°C for preheating, and the heating rate is 7°C / min; the temperature is rais...

Abstract

The invention relates to high-performance super-hard high-speed steel, which belongs to the field of metal materials. The high-speed steel contains w which accounts for 1.95-2.15% of total mass of the high-speed steel and Mo which accounts for 8.65-8.95% of total mass of the high-speed steel. The invention has the positive effect of improving cold and hot working properties of the high-speed steel.

Description

technical field [0001] The invention relates to a high-performance superhard high-speed steel, which belongs to the field of metal materials. Background technique [0002] The existing high-speed steel W2Mo9Cr4VCo8 has eutectic carbides of M 2 C.M 6 C, MC, M 23 C 6 and M 7 C 3 , tested by X-ray diffractometer, M 2 C accounts for 90-92.5%, M 6 C accounts for 3.0-4.5%, and the rest are MC and M 23 C 6 , M 7 C accounts for 3.0-4.7. After thermal processing and heat treatment, M 2 C→M 6 C+MC, M 2 C decomposition can refine carbides, but M 2 C often has insufficient decomposition, and the remaining amount is 1.0 to 3.0%. It is usually called rod-shaped carbide, and this rod-shaped M 2 The existence of C eutectic carbide not only affects the hot working performance of high speed steel, but also affects the service life of cutting tools. These factors hinder the application and development of high-speed steel W2Mo9Cr4VCo8. Contents of the invention [0003] The i...
