Nanolaminated (Cr,Mn)2AlC alloys by magnetron sputtering and ab initio calculations
(English)Manuscript (preprint) (Other academic)
We present an ab initio theoretical analysis of the temperature-dependent stability of hexagonal inherently nanolaminated (Cr1-xMnx)2AlC. The results indicate energetic stability over the composition range x = 0.0 to 0.5 for temperatures 600 to 900 K. Corresponding alloy thin films were grown by magnetron sputtering from four elemental targets. X-ray diffraction in combination with analytical transmission electron microscopy including electron energy-loss spectroscopy and energy dispersive X-ray spectroscopy analysis revealed that the films were epitaxial (0001)-oriented single crystals with x up to 0.16.
