Heat treatment method for adjusting alpha-beta-phase titanium alloy texture

The invention discloses a heat treatment method for adjusting an alpha-beta-phase titanium alloy texture. The method comprises the following steps that heating and heat preservation are conducted on forged alpha-beta-phase titanium alloy under the phase transition point, heat treatment is conducted, cooling is conducted, and transformation of the texture, adjustment of alpha phase content or elimination of defect textures can be achieved. The technological parameters of the method only comprise three parameters of heating temperature, heat preservation time and cooling way and are simpler than the parameters of forging, influencingfactors are few, the technological parameters and the shape of the obtained alpha-beta-phase titanium alloy texture can be in linear connection, direct relations of the texture and the technological parameters can be found from the perspective of scientific research, and from the perspective of industrial production, the stability of a technology and a product is improved advantageo
