Inhomogeneity of martensitic transformations in the rolled alloy Ti-50.3%Ni was investigated by use of X-ray texture diffractometry. For the first time temperature parameters of the reverse mortensitic transformation B19'→B2 were measured systematically for grains, corresponding by their orientation to 130 different points within a quadrant of the stereographic projection. Depending on grain orientations, the temperature interval of the reverse martensitic transformation has a width from 20° to 40°. Obtained data correlate with known regularities of strain hardening distribution in textured materials.
