Niobium-titanium alloy is attractive materials for industrials as a superconducting magnets to high critical magnetic field and supercurrent density at -283℃. The Nb-Ti alloy has been shown in earlier work to exhibit Van Gosh Sky microstructures. They may also be accentuated by plastic deformation due to work and temperature exposure during deformation. In the present study, we investigated the effect of normal, cross-roll and groove-roll rolling process the on the formability of Nb-Ti alloys. The specimens were processed into a strain of 2.0, 3.16 to 4.28 by rolling at room temperature and the rolled specimens were heat-treated in accordance with the time and temperature. Analysis of the α-Ti volume fraction and shape according to the rolling process and heat-treatment was carried out. In addition, the correlation between grain size and α-Ti formation position was analyzed.
