Effect of Initial Microstructure on the Mechanical Behavior and Evolution of Structure due to High-Temperature Stretching of VT9 Titanium Alloy

The effect of the initial structure of double-phase titanium alloy VT9 on the mechanical behavior and changes in the structure due to high-temperature uniaxial stretching is studied. Values of structural parameters after deformation are presented for six initial structural states of the alloy. The characteristics of uniform and lumped strain are computed. The effect of high-temperature annealing preceding the deformation on the ductility characteristics is described.
