Abstract:

Hydrogen embrittlement damage of metal materials used in hydrogen energy storage and transportation equipment has always been a key problem to be solved in the material industry, especially for the long-term safe operation of high-pressure hydrogen storage equipment. Up to now, the mechanism of hydrogen embrittlement damage of materials under hydrogen environment is still under continuous study. At present, by studying the adsorption and diffusion of hydrogen in materials and the relationship between hydrogen and crack initiation and propagation in materials, the hydrogen embrittlement mechanism of different metal materials has been preliminarily revealed. By studying the factors such as material types and hydrogen pressure, the main consideration points for material selection under hydrogen environment have been put forward.
