AB - Excellent soft magnetic properties of the amorphous and nanocrystalline alloys are attributed to their unique microstructure. In this work, Fe73.5Si13.5-xNb3Cu1B9Px (x = 0, 3.5, 7, 10 at. %) amorphous ribbons have been fabricated using the melt spinning technique. The effect of annealing temperature (475 ~ 600 ℃) on the microstructure and soft magnetic properties have been studied. According to the results, the thermal stability of FeSiNbCuBP amorphous alloys was improved by the partial substitution of Si by P. Moreover, it was found that the grain growth of α-Fe (Si) phase can be restrained by the appropriate amount of P addition and result to a grain refinement of the alloys during annealing. Base on refinement grain size (9 nm) and optimal crystallization volume fraction (47%), Fe73.5Si10Nb3Cu1B9P3.5 nanocrystalline alloy with low coercivity of 0.02 A/m and high effective permeability of 3.22 × 104 was developed after annealed at 525 ℃. Besides, we propose that the migration of free electrons from P to Fe could diminish the saturation magnetization of these alloys.
