| dc.description | To improve the magnetic properties of the hard-magnetic phase ?-Mn53.3Al45.0C1.7, it was mixed with different quantities of the soft magnetic phase Mn50B50 and annealed at different temperatures. Micrometric powders of the ? phase and the soft magnetic phase were mixed using solid-state procedures. The resulting magnetic properties were as follow: for the hard phase was saturation magnetization of Ms?=?38.22 Am2kg?1 at 1.8 T, remanent magnetization of Mr?=?20.10 Am2kg?1, coercive force of ?0Hc?=?0.378 T, and maximum energy product of (BH)max?=?3.09 kJm?3, and for the soft phase was Ms = 85.51 Am2kg?1 and a ?0Hc?=?0.018 T. After the preparation of different compositions of the mixture, and their annealing at different temperatures, it was concluded that the sample MnAlC/MnB with 2 wt.% of MnB phase annealed at 400 ? is the best one. Its magnetic properties were Ms?=?68.82 Am2kg?1 at 3.0 T, Mr = 36.26 Am2kg?1, ?0Hc?=?0.373 T and (BH)max?=?9.79 kJ m?3 which displays an improvement of about 7 kJ m?3 when compared to the original ? phase. Therefore, these magnetic properties are better than those shown by the pure ? phase. These properties were improved more when the sample was previously aligned and measured in parallel to the applied field. | |
