The multiplicity of possible structures was studied for several grain boundaries in the ordered compound Ni3Al. The interaction of lattice antisite defects with these grain boundaries was studied as well as the relaxation behavior of the lattice in the grain boundary region. Several interesting features were identified, like oscillatory behavior of defect formation energies as a function of the distance to the boundary plane. The dependence of grain boundary energy on composition is also discussed.
