Through-thickness macrotexture evolution of Ti-6Al-4V hot-rolled and annealed sheet was warm rolled to about 45% reduction at temperatures of 450oC, 600oC and 750oC, and was analyzed using orientation distribution function(ODF) in the study. The results show that the ND// fiber texture and the basal texture (0001)[2-1-10] or (0001)[1-210] , which can improve the mechanical property anisotropy of Ti-6Al-4V alloy, can be obtained by multipass warm rolling successfully. Moreover, the ND// fiber texture is developed in the bulk sheet, and the transverse texture (-12-10)[10-10] in the center layer varies with rolling temperature, whereas the basal texture in the surface layer is formed by accumulated shear strain from dislocation slip and its formation depends on initial orientation.
