Paper Abstract

The ways of the account of the plastic deformation of titanium-nickel mono- and polycrystals are considered. It is shown that a good description of the dependence of the yield limit on the orientation of the tension axis of a single crystal specimen can be achieved with the help of a condition of plastic slip, which takes into account the dependence of the flow stress on the stress tensor component acting on the shear plane in the direction perpendicular to the slip direction. For the calculation of polycrystal deformation the satisfactory conformity with an experiment can be received with the use of a model based on the classical Schmid law assuming the isotropy of the plastic slip on a shear plane.
