Peculiarities of the development of textures of rolling in thin sheet of pseudo-alpha-alloy of titanium of the system Ti-Al-V

Abstract

1. In sheets 2 mm thick of pseudo-α-titanium alloy of the system Ti-Al-V the rolling texture is distributed nonuniformly. In the layers of material close to the surface of the sheet we find texture of shear caused by base and prismatic slip. At the center of the sheet there predominates the texture of plane deformation of the initial prismatic orientation (\(11\bar 20\)) of the α-phase in rolling with great reduction in the temperature range M d e , the temperature of the end of martensitic transformation in deformation. 2. The effect of intermediate annealing of the billet before final rolling of thin sheet on the ratio of the fractions of material with the texture of phase transformation and the texture of plane deformation in it is connected with the sensitivity of the temperature of martensitic transformations in deformation to the initial structure and texture of the metal.
