Iron-based alloys with compositions close to Fe75Al25 (at.%) attract much attention due to their unique properties useful, e.g., for high-temperature or high damping engineering applications. Their mechanical, electron transport and magnetic properties strongly depend on the structural characteristics. In this paper we carried out a comparative study of the physical properties of the as spun ribbons Fe70Al30 and Fe70Al20Cr10 (at.%) alloys. The ribbons were produced using the melt spinning technique and were characterized by SEM, X-ray diffraction, differential scanning calorimetric, resistivity measurement and vibrating sample magnetometer. The addition of Cr to Fe70Al30 has a significant influence on atomic ordering, increases the electrical resistivity and a strong influence on the magnetic behavior.
Key words: Fe-Al(Cr) melt-spun ribbons / D03- and B2-type atomic order / heat treatment / resistivity / magnetization
