Abstract
The electronic charge transfer during the TiNi martensitic transition is pictured as a shift of the s band relative to the d band. Such a description not only is consistent with the earlier postulate that a portion of the valence electrons behaves covalentlike in TiNi II and metallike in TiNi III, but also gives a good account of the low-temperature specific heat, magnetic susceptibility, enthalpy, and Hall coefficient changes observed during the transition. The strength of electron correlation is calculated to be 1.1 eV; the work-function change during the transition is also about 1.1 eV.Keywords
