Abstract
The analysis of the Mossbauer spectra of (Cu0.8Fe0.2)(100-x))B-x the melt s pun ribbons taken at several temperatures between 4.2 K and room temperatur e allowed us to identify the occurring Fe-containing phases: alpha-Fe, gamm a-Fe and <(Cu)under bar>Fe solid solutions. The presence of B inhibits the phase transformation from fee to bcc Fe. For x = 0 and 1, the amount of Fe in the <(Cu)under bar>Fe solid solution is close to 3 at.% solubility limit , while for x=3 besides crystalline Fe3B, a supersaturated phase of 9.7 at. % Fe in the <(Cu)under bar>Fe solid solution was found, showing a strong de viation from the binary equilibrium phase diagram.
