Abstract
The electron structure and Ti L -absorption edge in the system Ti-Al-C have been studied theoretically using the
local coherent potential method of the multiple scattering theory. The alculated local partial electron density of states of
Ti made it possible to study the influence of Al on the electron structure of this material and its Ti L-absorption spectrum.
It was shown that in the ternary system comparing with the binary titanium carbide the first maximum of the titanium
unoccupied d-states nearly disappeared and the intensity of the second one fell more than twice. These calculations are in a
good correspondence with the experimental Ti L-spectra and indicate that the contribution of Ti s-states to XANES can be
neglected.
