Original Abstract

The uniaxial and hydrostatic deformation of martensitic structure B19' of NiTi shape memory alloy is studied using first-principles calculations. The bulk and Young's moduli and the theoretical strength under uniaxial tension and hydrostatic loading are computed from crystal response to applied deformations. The behavior of gamma angle of B19' structure was investigated along the whole deformation path. The computed values of Young's moduli are compared with available experimental results. The results obtained complement and extend the already known characteristics of NiTi alloy.
