Popis: | The microstructure, magnetic properties and corrosion behaviour of RE 16Fe7(1-x)M(x)Co5B8 (RE = Nd, Pr, Dy, Tb ; M = Si, Al, Cr) sintered magnets have been examined. It was established that the presence of Re-(Co, Fe, M) compound along the grain boundaries of these alloys was responsible for inhibition of the corrosion in acid solution and in atmospheric environment. The best magnetic properties obtained in these studies are Br = 1.26 T and MHc = 1 730 kA/m for the Nd14DyTbFe70SiCo5B8 alloy. |
