Addition of FeP powder to the sinterd 18Cr-2Mo-2Si-Fe magnetic alloy has been tried to improve its DC and AC magnetic properties. After sintering at 1200°C, DC magnetic property is most improved in 0.15 percent of P content, and DC magnetic property is most improved in 0.20 percent of P content. DC magnetic property increases with the sintering time, but in the initial stage AC magnetic property shows a change of increase and then decrease with time. Improvement of DC magnetic property by addition of FeP powder is attributable to the increase of the grain size and decrease of the porosity with the increase of the sintered density by the liquid phase sintering. On the other hand, enhancement of AC magnetic property may be attributed to the changes of structure originated from the formation of the solid phase of P and a small amount of residual phase accompanying the liquid phase sintering. The process of this structure change has been extensively discussed by the EPMA mapping analysis.
