Emission Mössbauer spectroscopy of grain boundaries in polycrystalline molybdenum

Grain boundaries in polycrystalline molybdenum have been studied by emission Mössbauer spectroscopy on 57 Co ( 57 Fe) nuclei. It has been shown that Co atoms diffuse along the grain boundaries by the interstitial mechanism. The states of Co atoms in grain boundaries and in near-boundary regions of t...
