A new method of combined loading was developed for manufacturing large - scale ingot of alpha-beta titanium alloy Ti-6Al-4V with the diameter of the gauge 120 mm and the length 300 mm. The process includes torsion with simultaneous tensile deformation, followed by a single compression and drawing of the ingot in alpha-beta temperature phase fields. Ingot structure and mechanical property evaluation was performed after deformation and post-deformation heating. The ingots had completely homogeneous macrostructure. The ingot microstructures were alpha plus beta with a mean grain size of d=10 m. There has not been any significant difference in microstructure of central and periphery areas in the cross section of the ingot.
