Abstract A new material was developed by introducing an organo-metallic polymer into powder metallurgy. In the uniform mixture of Fe- 13Cr* alloy powder and polycarbosilane (PC) usingn-hexane, the Fe-13Cr particles were coated with PC. The product of Fe-13Cr + 10wt% PC, obtained by hot-pressing the mixture, was subjected to an oxidation test, high-temperature hardness measurement and a wear resistance test, and found to be superior in all respects to that without the PC addition. The structure was observed by transmission electron microscope and it was found that grains of CrSi2 and Cr7 C3 about 0.1μm in size, dispersed uniformly in the Fe-13Cr + 10% PC, contributed to improvement of the mechanical properties. Observation by scanning electron microscope showed some difference in the formation of the oxidation film between Fe-13Cr and Fe-13Cr+10% PC. This new alloy, while adding an organo-metallic polymer to powder metallurgy, has several outstanding features with the possibility of many applications in the future.
