Abstract

The invention discloses a material performance test device applicable to a high-temperature vacuum environment. The material performance test device applicable to the high-temperature vacuum environment comprises a vacuum furnace box body. A heating device, a fixture for fixing a sample, and a deformation measurement component for measuring the deformation of a sample gauge length are arranged in the vacuum furnace box body; the heating device is used for heating the sample; the vacuum furnace box body comprises a first vacuum chamber and a second vacuum chamber; the heating device and the fixture are arranged in the first vacuum chamber; the deformation measurement component is arranged in the second vacuum chamber; a heat shield is arranged between the first vacuum chamber and the second vacuum chamber. According to the device, the deformation measurement component is kept in a normal operating temperature environment, so that the accuracy of an experiment test result is improved.

Description

technical field [0001] The invention relates to the technical field of material performance testing, in particular to a material performance testing device suitable for high-temperature vacuum environments. Background technique [0002] The mechanical properties of materials refer to the mechanical characteristics of materials when they are subjected to various external loads (tension, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, medium, humidity). For example, the high-temperature working parts of nuclear power, chemical industry, and electric power equipment, under the action of high-temperature non-oxidizing environment and stress, will cause the material performance of the equipment to deteriorate, and then the equipment will fail, seriously affecting the safe operation of the equipment. Therefore, material performance testing under the interaction of stress, high temperature and working environment has gradu...

Problems solved by technology

However, most of the existing high-temperature vacuum material performance testing devices adopt the form of the test environment of the sample and the overall heating of the deformation measurement component, and the deformation measurement component is under the action of the temperature field of the high-temperature environment, due to the different expansion and contraction of its internal parts. Deformation measurement components are not functioning properly resulting in less accurate experimental test results

[0003] In summary, how to solve the problem of low accuracy of experimental test results has become a technical problem to be solved urgently by those skilled in the art
