Formation energies of the impurities for interstitial and substitutional positions in hcp Ti lattice are calculated from “elemental” chemical potentials (μelement) and ‘oxide’ chemical potentials (μoxide), see Supporting information, that are listed in Tables 3 and 4, respectively. For example, Fig. 2a shows the … Zobacz więcej Titanium atoms occupying interstitial lattice sites are self-interstitials. In the hcp crystal lattice, a self-interstitial defect can be located at six … Zobacz więcej Chemical hybridization plays an important role for the configuration of impurity atoms in host lattices. An ideal measure of the orbital … Zobacz więcej The formation energy of an atom missing from a lattice site, i.e., a vacancy (VTi, not to be confused with vanadium substituted on Ti site, VTi), is calculated as where E is the total energy and the value of μTi derived from Ti … Zobacz więcej Witryna16 mar 2024 · The thermodynamic assessment of the Ti–O system has in the meantime confirmed the limit to about 33 at% over a broad temperature range for Ti–O. 4 Interstitial elements in the hcp crystal...
