In the article, the influence of the degree of hot deformation on the microstructure and mechanical properties of titanium alloy is studied. Structural changes and mechanical properties of 3M titanium alloy after hot plastic deformation of 80%, 84%, 86%, 90%, 93% degrees are given. The regularities of the effect of the main forging parameter, the degree of hot deformation, on the complex of mechanical properties of the 3M titanium alloy are established. Regularities of the effect of the main forging parameter (degree of hot deformation) on the structure of the 3M alloy are obtained. The dependence of the influence of the forging processing parameter (degree of hot deformation) on the final short-term properties of the 3M alloy is described. Thus, a complete picture of the entire process is obtained. The obtained results of the study make it possible to significantly deepen the knowledge about the relationship between the structural state and the mechanical properties of titanium alloy.
