    Abstract

    In order to develop a material having high erosive wear resistance at elevated temperature, the alloys of the ternary Fe-Cr-C system were produced by mechanical alloying (MA) and sintering process. Three kinds of alloys which have different contents of M23C6 carbide were made, and observation of the microstructure, measurement of the hardness and erosive wear test were carried out on each alloy. As a result the Fe-Cr-C alloys made by MA and sintering process have fine microstructure. The Vickers hardness of the MA-Fe-50% Cr-4.8% C alloy is more than 6 GPa at 973 K, and the erosive wear resistance of this alloy at 973 K is almost the same as that of sintered Cr3C2/Ni cermet, which is the commercially available material with high wear resistance.
