Harmonic lattice dynamics calculations have been performed on the low temperature structure of solid CT,,. The theoretically obtained lattice structure agrees with the experimentally determined low temperature structure and the symmetry is found to be P2,/m. The orientationally ordered equilibrium i
Observed changes in lattice parameter and resistivity with degree of order indicate T, N 190Β°C for the alloy &Au,; from Cowley's theory of order this yields v1 = 269k, V, = -26.9k, V, = 0, for the ordering interaction energies of pairs of atoms separated by the three shortest distances. The possibil
Based on the framework of systematic science of alloys, the basic information about states, volumes and potential energies of characteristic atoms in FCC Ti-Al system has been determined. For ordered FCC TiAl type alloys, the functions of the atomic states, atomic potential energies, cohesive energi
