| dc.description.abstract-en | A particular cathodic charging technique was used to evaluate the behaviour of hydrogen on Fe-25.66Ni-0.31C alloy. This technique is based on the electrolysis of water injected in a molten salts bath. The electrolytic charging conditions were chosen as −2.05V/Ag and 300°C. The quantities of hydrogen extracted from specimens of different diameters after electrolysis over different durations were used to calculate both the substantial surface concentration (C-0=3cm(3) H-2/cm(3) metal) and the hydrogen concentration profiles in austenite. After quenching at −65°C, a linear relationship between the hydrogen concentration and the amount of retained austenite was determined. A critical concentration C-k=0.06 cm(3) H-2/cm(3) metal, initiated microcracks in martensite. The behaviour of hydrogen on austenite is discussed in terms of grain boundary and dislocation trapping. | en |
