First principles calculation for the energies and magnetic moments of Fe2CrAl with various structures has been carried out. The contradiction between theoretical and experimental magnetic moment of Fe2CrAl has been illustrated. The L21-based structure has the lowest energy and thus should be formed during synthesis, while the native magnetic Cr-clusters are responsible for the extra large magnetic moment. Based on these calculations, a metastable and partially disordered B2CDstructure has been achieved in a ball-milled Fe2CrAl alloy. It shows a 300 K higher TCand a 1.5 μBhigher MS, respectively, compared with the arc-melted samples with L21-based structures.
