Single crystals of the alloy Ti-48%Ni-2%Fe, consisting of the phase B2, were rolled at 350°C with deformation degrees up to ~80% in 11 different initial orientations. Texture development in single crystals under rolling was analyzed to determine the active mechanisms of their plastic deformation. There are three stable initial orientations, which remain unchanged during rolling of Ti-Ni single crystals: {011}<011>, {111}<011> and {111}<112>. It was shown, that Ti-Ni single crystals deform by means of combined action of slip in systems {011}<001> and twinning in systems {114}<221> and {118}<441>. Variants of rolling texture formation in single crystals are very diverse and depend on their initial orientations and deformation degrees.
