Abstract

The recently formulated theory of vacancy formation in CsCl-type ordered alloys has been applied to β-NiGa and β-NiAl. The observed Nisublattice vacancy concentrations in these compounds could be well described by the theory. For the first time it is also shown that structural vacancies most likely exist in Ga-rich NiGa and Al-rich NiAl at absolute zero temperature.
