Magnetic properties of Sm(Fe,Ti)10 alloys and their nitrides
Source abstract
Abstract
Sm-Fe alloys with compositions of SmFe 10 and SmFe 9.5Ti 0.5 were prepared by rapid solidification processing. The as-quenched and annealed specimens did not show sufficiently high coercivity for use as permanent magnets, but the coercivity was improved by subsequent nitrogenation of the specimens. The specimens exhibited the maximum coercivity when nitrogenated at 743 K for 20 h in this study. The optimally nitrogenated SmFe 10 specimen consisted of the TbCu 7-type and α-Fe phases and showed a coercivity of 10.1 kOe, whereas the optimally nitrogenated SmFe 9.5Ti 0.5 specimen consisted of the Th 2Zn 17-type phase without the α-Fe phase and exhibited a high coercivity of 17.0 kOe.
