The electronic structure calculations for various phases in Me-Al-C systems (Me = Cr, Mn, Fe, Co, Ni) have been carried out using the full-potential linearized augmented plane wave (FP-LAPW) method. Possible crystal structures of non-stoichiometric carbides in these compounds are suggested. Electron density distribution, full and partial density of states spectra have been obtained. Type of magnetic ordering and varying of electronic properties depending on kinds of transition metal atoms in lattice and different carbon concentrations have been analyzed. We propose the hypotheses about effect of electronic structure of the carbon-containing phases that causing the diamond formation in these alloys.
