abstract = {Density functional calculations are used to investigate the
interatomic forces that arise if Ti atoms are substituted by
Ni or Cu defect atoms. For the experimentally found
monoclinic B19’ ground state structure, these forces are
calculated for the unrelaxed atomic positions by the
Korringa–Kohn–Rostoker Green-function method. The force
field in the vicinity of the defects is markedly different
in 32- and 256-atom supercells while it is nearly the same
in 256- and 2048-atom supercells. This difference is
explained by symmetry arguments and discussed as a possible
explanation for the concentration dependent transition from
the high-temperature B2 phase to low temperature B19’ or
strain glass phases.},
