“…These carbides are in the complex form (Fe 3 C) x (Al 4 C 3 ) y and dissociate into graphite when the aluminum content increases from 15 to 17 wt pct. Etter et al [24] and Urena et al [25] also observed small sticks of Al 4 C 3 for the processing of Al-C composites, when graphite and liquid aluminum are both in contact.…”

“…These precipitates are too small to be analyzed by the SEM available in the laboratory, but assumptions concerning their nature can be proposed from studies reported in the literature. The precipitates either should be small graphite lamellas [23] or aluminum carbides formed by the decomposition of the pearlite of the steel [11,24,25] as follows:…”

International audienceThe corrosion mechanisms by liquid aluminum of three industrial materials have been studied: unalloyed steel (UAS), and ferritic and modified pearlitic cast irons (FCI and PCI, respectively). The behavior of these materials when in contact with liquid aluminum is different. Aluminum diffuses deep into the UAS and forms intermetallic compounds with iron at the surface and in the steel matrix. At the surface, only Fe2Al5 and FeAl3 are found. In the matrix, FeAl2 also is formed in agreement with the equilibrium Fe-Al diagram. From the matrix to FeAl2, the Al content in the ferrite increases progressively until Al saturation is reached. At this step, black elongated precipitates (Al4C3 and/or graphite) appear. Graphite lamellas present in both FCI and PCI constitute an efficient barrier to the Al diffusion. The high silicon content of the FCI leads to the formation of a phase free from Al and saturated in Si. For the PCI, a thin layer rich in Al and Si, which is formed between the matrix and Fe2Al5, limits the diffusion of atoms. The effects of Cr and P added in the PCI also are discussed

The mechanical model was established for the anti-plane fracture problem of a functionally graded coating-substrate system with a coating crack inclined to the weak/micro-discontinuous interface. The Cauchy singular integral equation for the crack was derived using Fourier integral transform, and the LobattoChebyshev collocation method put up by Erdogan and Gupta was used to get its numerical solution. Finally, the effects of the weak/micro-discontinuity of the interface on SIFs were analyzed, the "affected regions" corresponding to the two crack tips have been obtained and their engineering significance was discussed. It was indicated that, for the crack tip in the corresponding "affected region", to reduce the weak-discontinuity of the interface and to make the interface micro-discontinuous are the two effective ways to reduce the SIF, and the latter way always has more remarkable SIF-reduction effect. For the crack tip outside the "affected region", its SIF is mainly influenced by material stiffness, and to prevent such a tip from growing toward the interface "softer coating and stiffer substrate" is a more advantageous combination than "stiffer coating and softer substrate".
