ResumoSome Fe3AlCx and Ni3AlCx alloys with various microstructures were tested with respect to strength and ductility between room temperature and 1200 °C. The studied Ni3AlCx(+ Mn, Fe) alloys show the perovskite-type structure (L′12) with up to 2.5 at% carbon and are single phase. The Fe3AlCx alloys show the same perovskite-type structure, which is stable in this case only for carbon contents exceeding 11 at%. These alloys contain precipitates of graphite or α-FeAl (B2). All alloys were studied by compression tests with constant deformation rate or constant load. Additionally, some hot-hardness tests were carried out. Ductility was characterized by 4-point-bending tests. The properties of Fe3AlCx and Ni3AlCx alloys are compared to each other and to those of Ni3Al.
