Microstructure and tensile properties of Fe_3 Al-based alloys with additions of TiC and VC particles have been investigated. Results show that the formation of TiC particies results in the refinement of the macrostructure of as-cast ingots. Although the addition of VC particles does not cause significant change of the as-cast microstructure, the microstructure of the alloy after hot-working and recrystallization has been found to be refined. The formation of both VC and TiC particles results in the increase of yield strength, especially at high temperature of 600℃.
