摘要：In the process of free forging an ingot made of titanium alloy with an alpha +beta structure is subjected to multiple plastic deformation in its axial, radial, andtangential directions with an overall degree of deformation in each of these directionsbeing not less than 60 percent of the total deformation, and with sucessive changing ofthe direction of the deforming force. On completion of deformation annealing is
performed at a temperature somewhat below the temperature of phase transformation
of the alloy from beta to alpha + beta structure.
