Experimental results of the microstructure changes of the B2 phase before the B2 B19 ' martensitic transformation are presented in the paper. The neutron diffraction patterns from the B2 phase of the Ti 49Ni 51 single crystal were obtained in the wide range of the reciprocal space. The neutron diffraction features in the  , direction and perpendicular to it are in details investigated in the work.
