The (Sm,Zr)(Fe,Co)(5) alloys were prepared using the melt-spinning technique and subsequent annealing. Substituting Zr for Sm stabilized the SmFe5 phase and increased coercivity, while substituting Co for Fe further increased coercivity. The optimal annealing temperature and composition of the alloy led to a high coercivity of 4.75 kOe without nitrogenation.
The (Sm,Zr)(Fe,Co)(5) alloys were prepared by the melt-spinning technique and subsequent annealing. The substitution of Zr for Sm stabilized the SmFe5 phase and resulted in a small increase in coercivity, while the substitution of Co for Fe also stabilized the SmFe5 phase and produced a slightly higher increase in coercivity. The substitution of both Zr for Sm and Co for Fe not only stabilized the SmFe5 phase but also significantly increased the coercivity. The (Sm,Zr)(Fe,Co)(5) alloy with the optimal annealing temperature and composition exhibited a high coercivity of 4.75 kOe without nitrogenation. (C) 2020 Elsevier B.V. All rights reserved.
