| Abstract: | The theoretical model to calculating critical hydrogen concentration was
reviewed using Devanathen's hydrogen permeation method. The distribution of hydro-
gen coneentration along the direction of hydrogen permeation and the critical hydro-
gen concentration during hydrogen--induced crack growing, mainly along MnS inclu-
sion interfaces, in the hardened and tempered steel 20 have been determined. The al-
lied problems were also discussed briefly. |
