Abstract
Mössbauer effect spectroscopy has been used to follow the temperature and time dependence of the clustering, precipitation and oxidation of Fe atoms in a metastable Cu-0.2 at.% Fe alloy. Spectra were obtained from 298 K to 919 K in regular intervals. The solubility of Fe in Cu was found to be 2000 at.ppm at 891 ± 10 K. Internal oxidation of the Fe occured above 843 K in a vacuum of about 10-5 torr. The oxidation product has Mössbauer parameters which are not characteristic of FeO, Fe2O3, Fe3O4 or CuFeO2Keywords
