Abstract

MA powder of Fe-Cr-C was prepared by mechanical milling of powders of chromium, carbon and iron in an argon atmosphere for 200 h. MA compacts were hot-pressed at 1273 K for 3 h. A uniform structure of a-phase and M23C6 with a diameter of approximately 1 mm was observed. Fe-Cr-C MA alloys were evaluated on erosive wear resistance using the centrifugal erosion apparatus. In particular, Fe-50 mass% Cr-4.8 mass% C alloy showed wear rate less than 1/5 of that of Mod. 9Cr-1Mo steel and showed high wear resistance at medium and high impingement angles.
