摘要
The influence of temperature on hydrogen diffusion and hydrogen embrittlement of X80 steel was studied using electrochemical hydrogen charging. The hydrogen diffusion and subsurface hydrogen concentration in the steel increased with increasing the temperature. Macro slow strain rate tensile tests and microstructural analysis were performed to unveil the dependence of hydrogen-induced embrittlement susceptibility on temperature, which suggested a temperature threshold THE, max of 315 K. The demonstration of THE, max would be crucial for determining test temperatures of hydrogen-related engineering material applications.
