Diffusion Of Hydrogen

An electrochemical technique was used to measure the room temperature diffusivity and trapping of hydrogen in a 0.82%C steel for chemical pressure vessels in two micro structural conditions (a) the cold worked pearlitic state and (b) the hardened and tempered state. Trapping of hydrogen occurs in both structures but with more traps in the cold worked structure. Base on experimental results and observation, different hydrogen retention (trapping) behavior operates in the two structures. It was also found that patented and cold worked steels are much less susceptible to hydrogen induced embrittlement than similar steels in the hardened and tempered condition. Key words: Diffusivity of hydrogen; hydrogen embrittlement; cold–worked

Surface Observations

In order to investigate the susceptibility of steels to hydrogen embrittlement as a function of their microstructure X70 steel was chosen in different conditions: normalized transfer bar, as-received hot rolled strip and heat affected zone (HAZ). Notched and fatigue pre-cracked samples were subjected to electrochemical hydrogen charging to achieve 2 ppm hydrogen content. Three point bend tests were conducted on as-received and hydrogen charged samples. The results showed that HAZ samples are more susceptible to hydrogen embrittlement than the others. This was supported by fracture surface observations.
