抄録

Since Fe<SUB>4</SUB>N decomposes at 670°C, sintering of Fe<SUB>4</SUB>N powder has not been performed under atmospheric pressure. In this study, Fe<SUB>4</SUB>N powders have been sintered below the decomposition temperature applying hipping pressure. The sealed capsule containing Fe<SUB>4</SUB>N powder was hipped at 450-550°C for 2 hours under 50-200 MPa. The decomposition of Fe<SUB>4</SUB>N was confirmed at 550°C. Therefore, hipping temperature was restricted below 500°C. The maximum relative density 97% was obtained for the specimen hipped at 500°C under the maximum pressure of 200MPa. The specimen obtained at 450°C has a higher saturation magnetization than that obtained at 500°C. The maximum saturation magne-tization 182emu/g was measured for a specimen obtained at 450°C under 200 MPa. The saturation magnetization was decreased to 151 emu/g by the addition of small amount of oxygen (0.33wt%) to Fe<SUB>4</SUB>N raw powder. In addition, the corrosion resistance of the hipped Fe<SUB>4</SUB>N was higher than that of steel.
