Abstract An addition of small amount Ce to Fe_3Al increases significantly theroom temperature strength, and a mixed addition of Ce and Cr improves both strengthand ductility. The fracture mode of Fe_3Al containing Ce is a mixed one of ap-proximately 70% transgranular cleavage and 30% intergranular failure. The disloca-tions observed are mainly single ones with b=1/4a′_0<111> in the deformed specimensof bare binary Fe_3Al, but a number of super-lattice dislocations in that with Cradded.

Key words: Fe_3Al intermetallics mechanical property superlattice dislocation
