Abstract
Grain boundaries (GBs) in pure Cu specimens were studied by means of Fe-57 emission Mossbauer spectroscopy. A spectrum component which can be ascribed to iron atoms at GBs is represented by the single line with isomer shift 0 .67 +/- 0.05 mm/s. It is interpreted as iron atoms at GB sites with expande d atomic volumes and highly symmetric distribution of surrounding atoms.
