Abstract: FeSiCr soft magnetic alloy powder was prepared by water atomization method, and the effects of melt temperature, atomization pressure and atomized water flow rate on the properties of alloy powder were systematically studied. The particle size, morphology, oxygen content, bulk density and fluidity of the powder were tested and analyzed by means of laser particle size analyzer, scanning electron microscope, oxygen nitrogen analyzer and Hall flowmeter. The results showed that with the increase of atomization pressure and melt temperature, the particle size of powder become smaller. The atomization water flow rate was reduced, the powder morphology was more regular, and the particle size and bulk density were increased. The best atomization process: the ato-mization pressure was 50 MPa, the melt temperature was 1 750 ℃ and the water flow rate was 15.24 L/min. The prepared FeSiCr soft magnetic alloy powder had low oxygen content, small average particle size and regular morphology.
