Hydrogen Embrittlement and Mössbauer Effect

Popis výsledku v původním jazyce

In this study we measured in transmission technique Mössbauer effect on alpha Fe foil. The spectrum was excellent and we used these data for calibration of Mössbauer equipment. After this we putted foil into special electrochemical cell with small narrowreservoir and electrochemically polarized one part of foil as cathode in acid solution (0.13 mol HCl). On this part of foil can take place reaction hydrogen proton or electrical and chemical excited state of hydrogen with the surface of iron and can diffuse into foil. During a 30 minute when alpha Fe foil was under cathodic condition, the Mössbauer effect was different, because width of spectrum was different was large. We think, that hydrogen pressure diminish or suppresses magnetic dipole and electric quadrupole interactions and influences electric dipole moment in the sample. It knows, that width and the position of the center of Mössbauer spectrum depends on the inner pressure in the solid phase and can inform about inner stress in
