On the sintered 12.5 percent chromium-iron magnetic alloy added Fe-P powder from 0.4 to 1.2 percent, the change in the magnetic properties with the sintering time at 1200°C was mainly studied in making use of the EPMA mapping analysis . After sintering for 1 hour, DC and AC magnetic properties come to the maximum value by the addition of 0.6 and 0.8 percent Fe-P respectively. The sintered density increases with the increasing of sintering time and DC magnetic properties increase monotonously in the same way. However, AC magnetic properties show a specific inclination to firstly increase and then decrease with sintering time. It was comfirmed by the EPMA mapping analysis that these changes in the magnetic properties originate from the phenomena of the liquid phase sintering, the solid solution of P and its remaining at the grain boundaries caused by Fe-P addition of over 0.8 percent.
