Description

A detailed phase analysis of mechanically alloyed (Sm0.18Co0.82)100-xFex powders has been performed using X-ray diffraction and Moessbauer spectroscopy. A two-phase structure develops as the Fe content is increased, with an increasing proportion of bcc Fe-Co in addition to amorphous Sm-Co-Fe. Both phases become richer in Fe, but Fe is concentrated in the bcc phase, due to a limited ability of Fe to substitute in amorphous Sm-Co. Changes in phase formation with increasing Fe content can be correlated with changes in the calculated free energy of mixing of amorphous Sm-Co-Fe
