The change of TiNi surface electronic structure during B2-B19 ' martensitic transformation

The electronic structure of different surfaces for B2- and B19'-TiNi were investigated using the full-potential linearized augmented plane wave method in the local density approximation. The changes of the electronic structure on the surface in comparison with bulk is analyzed in both phases. It is shown that surface electronic structures change insignificantly upon martensitic transformation. The initial oxidation of B2-TiNi (001) surface is also discussed.110sciescopu
