Correlation of the Mossbauer Effect and Hydrogen Embrittlement of AISI 4340 Steel.
Abstract
The relationship between Mossbauer Effect parameters and hydrogen embrittled steel was examined. The 14 keV gamma-rays were used for observation, penetrating a cadmium plating that slowed out-diffusion of the hydrogen. Standard 'around-the-corner' backscatter geometry was used. AISI 4340 steel, heat treated to strength levels of 260 - 280 ksi was used. Samples were in the form of C-rings with a notch located to permit destructive testing as a cross-check. Computer fitting was used to reduce the data. No correlation was observed between embrittled and unembrittled specimens. All variations in the data were within the standard deviation observed.
