Abstract: 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)₁₂ N_x in turn after having been arc melted in a purified argon, homogenized, melt-spun, annealed and nitrided. The magnetic properties are obtained on vibrating sample magnetometer(VSM). After annealing at 760℃ for 30 min and nitrided at 600℃ for 2 h,B_r is 0.349 T and H_c is 115.4 kA·m^-1.
