Influence of defects (Ti vacancy and Nb dopant) on the bonding of TiAl/TiO 2 interface was studied via first-principles calculations. It was shown that the bonding strength and the stability of TiAl/TiO 2 interface were weakened by the presence of Ti vacancy and dopant Nb. The defects could also change the relative stability of the interface with different couplings between the two...
A mean-field model is proposed to estimate the atom-atom and atom-vacancy bond energies of intermetallic compounds, with the results of first principles calculations as input. The variation of point defects with temperature and chemical composition estimated with the model agreed with experimental measurements for TiAl and NiAl alloys. In particular, off-stoichiometric effect considered in this treatment...
