Effect of Cr addition and heat treatment on the physical properties of Fe-Al melt-spun ribbons
Abstract
<jats:p>Iron-based alloys with compositions close to Fe<jats:sub>75</jats:sub>Al<jats:sub>25</jats:sub> (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 Fe<jats:sub>70</jats:sub>Al<jats:sub>30</jats:sub> and Fe<jats:sub>70</jats:sub>Al<jats:sub>20</jats:sub>Cr<jats:sub>10</jats:sub> (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 Fe<jats:sub>70</jats:sub>Al<jats:sub>30</jats:sub> has a significant influence on atomic ordering, increases the electrical resistivity and a strong influence on the magnetic behavior.</jats:p>
