System and method for evaluating reaction behavior of non-oxide materials under complex stress

Abstract

The present invention provides a system for evaluating the reaction behavior of a non-oxide material under the action of complex stress, which includes being arranged on the non-oxide material sample for providing stress to the sample when evaluating the reaction behavior of the sample Field stress control means for providing a temperature field to the sample when evaluating the reaction behavior of said sample Temperature control means for providing an atmosphere field to the sample when evaluating the reaction behavior of said sample device. The invention also provides a method for evaluating the reaction behavior of the non-oxide material under complex stress. The system and method for evaluating the reaction behavior of non-oxide materials under complex stress provided by the present invention can realize the coordinated control of the temperature field, atmosphere field and stress field in the reaction process of the sample, and then under conditions closer to the actual service environment Evaluation of the high-temperature interfacial reaction behavior of non-oxide materials.

Description

technical field [0001] The invention relates to the technical field of performance research of inorganic non-metallic materials, in particular to a system and method for evaluating the reaction behavior of non-oxide materials under complex stress. Background technique [0002] High-temperature industries such as iron and steel metallurgy are important basic industries of the national economy, and their long-term and stable operation in extreme environments cannot be separated from the strong guarantee of high-temperature structural materials (ie refractory materials) used as linings. Compared with oxide materials, non-oxides (carbides, nitrides, borides, etc.) and their composite materials have better thermal shock stability and slag erosion resistance. Compared with traditional carbon composite materials, this type of material not only has high strength and excellent oxidation resistance, but also basically does not pollute molten steel. Therefore, they are ideal materials...

Problems solved by technology

However, the existing devices are difficult to precisely control the stress, temperature and atmosphere of non-oxide materials in the service environment at the same time, and cannot effectively simulate the high-temperature interface behavior of materials in a stress-temperature-atmosphere coupling environment, which is not conducive to materials under actual working conditions.
