First-principles calculations are presented for parent B2 phase and martensitic B19 and B19 0 phases in NiTi. The results indicate that both B19 and B19 0 are energetically more stable than the parent B2 phase. By means of ab initio density functional theory, the complete distortion-shuffle energy l
