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

Abstract

The invention relates to a high-temperature-deformation-resistant high-strength platinum group metal material and a preparation method. The material is composed of platinum group metal and a strengthening phase, and the strengthening phase is any one or more of zirconium oxide, yttrium oxide and titanium carbide particles dispersedly distributed in the platinum group metal; the material comprisesthe following components including, by weight, larger than 0 and smaller than or equal to 0.4% of the strengthening phase and the balance platinum group metal. The material has high strength, excellent deformation resistance, electric ablation resistance, scouring resistance, corrosion resistance and high-temperature creep resistance in a specific environment at a high temperature, especially at ahigh temperature condition being 1400 DEG C or above, an assembly prepared from the material is good in high-temperature deformation resistance and long in service life, and the production cost in the application field can be effectively reduced.

Description

Technical field [0001] The invention belongs to the field of metal materials, and particularly relates 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), resist deformation, resist electric ablation, resist erosion, and resist corrosion. Platinum group metal materials are widely used due to their excellent properties such as high melting point, oxidation resistance and corrosion resistance. Platinum group metal material is a highly advantageous high-temperature metal material, but its high-temperature mechanical properties are poor. The prior art uses solid solution strengthening and second phase internal oxidation strengthening methods in the platinum group metal matrix to improve its high-temperature mechanical properties to a certain extent, but it is limited by ...

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
