The fraction of hydrogen-induced H martensite and mechanical properties of hydrogen-charged austenitic steels were studied as a function of their chemical composition. It is shown that alloying elements affect the intensity of β₯ β H transformation due to their influence on stacking fault energy. A d
Three main available hypotheses of hydrogen embrittlement are analysed in relation to austenitic steels based on the studies of the hydrogen effect on the interatomic bonds, phase transformations and microplastic behaviour. It is shown that hydrogen increases the concentration of free electrons, i.e
