Abstract
Some Fe3AlCx and Ni3AlCx alloys with various microstructures were test ed with respect to strength and ductility between room temperature and 1200 degrees C. The studied Ni3AlCx(+Mn,Fe) alloys show the perovskit e-type structure (L'1(2)) with up to 2.5 at% carbon and are single pha se. The Fe3AlCx alloys show the same perovskite-type structure, which is stable in this case only for carbon contents exceeding 11 at%. Thes e alloys contain precipitates of graphite or alpha-FeAl (B2). All allo ys 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. (C) 1997 Elsevier Science Limited.
