Device for testing material properties in high-temperature hydrogen environment

Abstract

The invention relates to a device for testing material properties in a high-temperature hydrogen environment. The device comprises a hydrogen environment box and a host machine loading framework, wherein a test sample is arranged in the hydrogen environment box; a pull rod is mounted on the host machine loading framework; the hydrogen environment box is arranged on the host machine loading framework; an upper clamping part, a lower clamping part and an electrical heating component are arranged in the hydrogen environment box; the pull rod penetrates through the hydrogen environment box and is fixedly connected with the lower clamping part; the hydrogen environment box is connected with a hydrogen supply pipe; an air-relief solenoid valve is arranged on the hydrogen environment box. The device further comprises sensors and a control component, wherein the sensors are used for monitoring test sample stress load, test sample deformation, test sample environment temperature and test sample ambient hydrogen pressure; the control component is used for monitoring and processing the information collected by the sensors. The device can be used for testing the creep property, stress rupture property and tension-tension alternating load fatigue property of a metal material in the hydrogen environment, can ensure the accuracy of testing results, works reliably and stably and has high efficiency.

Description

technical field [0001] The invention relates to the field of material performance testers, in particular to a high-temperature hydrogen environment material performance test device. Background technique [0002] Chemical hydrogen equipment is often subjected to the interaction of stress-high temperature and hydrogen medium, which leads to the deterioration of the material properties of the equipment, and then the equipment fails, which seriously affects the safe operation of the equipment. For this reason, the material performance test and its test device under the interaction of stress-high temperature and hydrogen medium are very important. However, due to the flammable, explosive and easy-to-leak characteristics of hydrogen, the existing material performance test device cannot simultaneously realize complex stress-high temperature. And the performance test of metal materials in hydrogen environment. Therefore, there is an urgent need for a high-temperature hydrogen envir...
