σ-Phase in the Fe50Cr50 alloy

We report a detailed study of σ-phase formation in the Fe50Cr50 alloy. Our results demonstrate that the σ-phase forms only in a surface layer no more than 0.3 mm in thickness. In the bulk of the alloy, the formation of the σ-phase is prevented by a metastable domain structure in which chemical domains have opposite signs of ordering energy.
