    The influence of the additions of the mass fractions 3% of Fe and 1% of Ce to an AlCr4Ti0.4 alloy is described in this paper. The iron addition modifies the phase composition of the material leading to the formation of the Al13Fe4 crystalline and Al-80(Cr,Fe)(20) quasicrystaline phases. It also causes a grain refinement that was proved with transmission electron microscopy and X-ray diffraction. The microhardness of the Fe-alloyed material is changed by about a factor of two in comparison to the material without Fe. On the other hand, the Fe addition has no influence on the thermal stability of the alloy. The effect of 1% of Ce on the AlCr4Ti0.4 alloy hardly affects the microhardness but increases the thermal stability during long-term annealing at 400 degrees C.
