Microscopic deformation of a Ti-17at. %Nb alloy with high fractions of α"-martensite and ω phases was studied by in-situ synchrotron X-ray diffraction. Textures, phase fractions, individual lattice strains, and peak intensities during deformation were studied. It is found that, to accommodate the external tensile strain, some of the α" and ω grains were first transformed to the β-phase, which then continuously transformed to the α"-phase with chosen variants that effectively accommodate the deformation strain. Here, a strong (010)α" fiber texture was formed at the expense of the (001)α" and (111)α" fiber textures. Above 400 MPa applied stress, (110)α" deformation twinning was triggered with a simultaneous stress relaxation in the (110)α" family and a slight increase in its texture strength in the loading direction.
