摘要:
The textures of the beta- and alpha-phases of the metastable beta-titanium alloy Ti5321 after hot deformation were investigated by neutron diffraction. A hot-rolled bar was solutionized in the beta-phase field and then hot compressed above and below the beta-transus temperature. The initial texture after full recrystallization and grain growth in the beta-phase field exhibits a weak cube component {001}<100> and minor {112}<110> and {111}<110> components. After hot compression, a <100> fiber texture is observed, increasing in intensity with compression temperature. Below the beta-transus temperature, dynamic recrystallization of the beta-phase and dynamic spheroidization of the alpha-phase interact strongly. The texture of the alpha-phase is a <11-20> fiber texture, increasing in intensity with decreasing compression temperature. The mechanisms of texture formation during hot compression are discussed.
