Abstract

Fe-0.8% P soft magnetic alloy was prepared by powder metallurgy. The compressibility and purity of powder were improved through collocation of powder particles and annealing treatment. The effect of sintering temperature on density, microstructure, and magnetic properties of the alloys was studied. Results show that the magnetic performance of the alloy was enhanced due to increased density because of the formation of liquid phase at low temperature and δ phase at high temperature. The optimum magnetic properties of Fe-0.8% P alloy with magnetic induction (B6000) of 1.83 T, maximum permeability of 18706 and coercive force of 30 A m−1 were obtained due to increased density (relative density 99.4%) and sintering temperatures.
