The precipitation of carbide particles and high temperature strength in a Fe3Al base alloy with C, Cr and Mo were investigated. The -Fe3AlC (E21) and M2C (B81) phases precipitated in the temperature range between 1000 C and 600 C in periods up to 10 h. The -Fe3AlC phase tended to precipitate in a film-like morphology on grain boundaries by annealing at relatively high temperatures. The M2C phase was dispersed in a fine needle shape within grains by annealing at 700 C. The film-like precipitates covering grain boundaries as well as finely dispersed M2C particles was suggested to contribute to strengthening at 600 C.
