High-strength platinum group metal material resistant to high temperature deformation and preparation method

Abstract

The invention relates to a high-strength platinum group metal material resistant to high temperature deformation and a preparation method. The material is composed of a platinum group metal and a strengthening phase, and the strengthening phase is zirconia, yttrium oxide, and titanium carbide particles dispersed in the platinum group metal Any one or several of them, the weight percentage content of each component of the material is the strengthening phase>0~≤0.4wt%, and the platinum group metal is the balance. The material has high strength and excellent resistance to deformation, electric ablation resistance, erosion resistance, corrosion resistance and high temperature creep resistance at high temperatures, especially at 1400 ° C and above. The components have good resistance to high temperature deformation and long service life, which can effectively reduce the production cost in the application field.

Description

technical field [0001] The invention belongs to the field of metal materials, in particular to a high-strength platinum group metal material resistant to high temperature deformation and a preparation method. Background technique [0002] The industrial field needs to widely use metal materials that can withstand high temperatures (especially above 1400°C) to resist deformation, electric ablation, erosion, and corrosion. Platinum group metal materials are widely used because of their high melting point, oxidation resistance, corrosion resistance and other excellent properties. Platinum group metals are extremely advantageous high-temperature metal materials, but their high-temperature mechanical properties are poor. In the prior art, the high-temperature mechanical properties of the platinum group metal matrix have been improved to a certain extent by means of solid solution strengthening and internal oxidation strengthening of the second phase particles. , so that the hig...

Problems solved by technology

With the advancement of industry, the requirements for materials are becoming more and more stringent. The platinum group metal materials prepared by the existing technology are resistant to deformation, electric ablation, and erosion in a specific environment in a high temperature environment, especially at a high temperature above 1400°C. , Corrosion resistance cannot meet the expected requirements, making components made of these materials easy to creep and deform under high temperature conditions, and the service life is short
