The B2 FeCo alloy is of great interest for high-temperature applications in the automotive industry as actuators due to its high saturation magnetization and Curie temperature. However, this alloy suffers from low ductility at room temperature. In this study, density functional theory applying the supercell approach was used to investigate the mechanical and magnetic properties of B2 Fe50Co50-XCrX (0 ≤ x ≤ 50) structures. The stability of Fe50Co50-XCrX was evaluated from the heats of formation, magnetic properties, and phonon dispersion curves. The heats of formation showed that doping with Cr enhances the thermodynamic stability of FeCo. Furthermore, the calculated Pugh and Poisson’s ratios revealed that doping with Cr effectively enhances the ductility of FeCo. Thus, the results suggest that the B2 Fe50Co50-XCrX alloy can be used for the future development of magnetic components with good strength in the automotive industry.
