Fig. 3: Phase structure of the quinary o-MAXs and schematic of the ordering inherits.

From: Miscible chemical ordering in Ti-Cr-Mo quinary system by solid solution of Mo2Ti2AlC3 and Cr2.5Ti1.5AlC3 o-MAXs

a Rietveld refinement of XRD pattern for annealed Mo1Cr2 MAX. The diffraction patterns of MAX and TiC phase are derived from the standard crystallographic data of α-V4AlC3 (ICSD 160754) and TiC (ICSD 1546). b The change in lattice parameters of the three quinary o-MAXs compared to Cr2.5Ti1.5AlC3 and Mo2Ti2AlC3. The red and blue plots correspond to the parameters of a-axis and c-axis, respectively, whereas the green plot shows the c/a ratio. c Schematic illustration of the stoichiometric solid solution of Cr2.5Ti1.5AlC3 and Mo2Ti2AlC3 to form the quinary o-MAX and the succession of the out-of-plane ordering. The red and blue knight phalanxes refer to the lattice of Cr2.5Ti1.5AlC3 and Mo2Ti2AlC3, respectively, whereas the equipped shield and spear, respectively, represent the 4e and 4f metal sites in each o-MAX.
