摘要

The phase transition of melt-spun Pr_1.4Fe_10.5Mo_1.5 and its nitrides have been studied by means of XRD and TEM. The phases of the alloy are α-Fe(Mo) (containing a little of other phases), Pr(Fe, Mo)_12, Pr(Fe, Mo)_7, Pr(Fe, Mo)_12 and Pr(Fe, Mo)_12N_x in turn after having been arc melted in a pu- rified argon, homogenized, melt-spun, annealed and nitrided. The magnetic properties are obtained on vibrat- Ing sample magnetometer (VSM). After annealing at 760 deg. C for 30 min and nitrided at 600 deg. C for 2 h, B_r is 0.349 T and H_c is 115.4 kA·m~-1.
