Orientation relationships and interfaces in directionally solidified eutectics for solid oxide fuel cell anodes

Calculation of the Orientation Relationships of Directionally Solidified Eutectic Ceramics by a Modified Coincidence of Reciprocal Lattice Points Model (CRLP)

“…This is reasonable, since actual ORs are not only influenced by the geometric coherence of the phases, but also by the formation of low‐energy interfaces which, in the case of DSECs, are thought to derive from a good balance of ionic charge density at the interface . This was the case of OR1, considering that it shows little misfit between the ionic charge density of each phase . Yet, as explained before, interface planes for the cube‐on‐cube OR remain unclear and are not expected to be as energetically favorable as those in the majority OR.…”

“…Thus, in this article, we have tested a modification to the CRLP method in order to take into account the parallelism between low‐Miller‐index planes criterion, and we show the results of applying this model, with and without the modification, to a family of DSECs (NiO–YSZ, CoO–YSZ, NiO–GDC, NiO–CeO 2 , CoO–GDC, and CoO–CeO 2 ) prepared by the laser floating zone technique. Growth directions, ORs, and interface planes for these materials were experimentally determined by means of Electron Backscattering Diffraction (EBSD) in a previous article, in which the application of the CRLP method to the NiO–YSZ eutectic was advanced …”

Directionally Solidified Boride and Carbide Eutectic Ceramics

“…28,35,36,72,73 The strong crystallographic texturing along the solidification direction can lead to anisotropic material properties, and is thus an important attribute of the eutectic composite. 28,35,36,72,73 The strong crystallographic texturing along the solidification direction can lead to anisotropic material properties, and is thus an important attribute of the eutectic composite.…”

Electron backscattering diffraction as a complementary analytical approach to the microstructural characterization of ancient materials by electron microscopy

“…Surface preparation was accomplished using a progressive lapped and polishing method previously tested on ceramic samples [46]. Thus, the specimens were first ground with SiC paper (P2500 and P4000) using a polishing wheel at 40 rpm and a load of 2.5 N. They were then polished with diamond slurry (3 µm and 1 µm of particle size, 120 rpm, 2.5 N load, 3 minutes each step) and with colloidal silica (OP-U Suspension from Struers, Denmark) at 100 rpm for 15 minutes.…”
