Abstract
This study shows the effect of the specific impact-oscillatory loading (Dynamical nonequilibrium process) on the VT-22 titanium α+β-type alloy mechanical properties and microstructure. Experiments were conducted using modified universal testing machine. Physical research revealed that significant microstructural refinement of the alloy is observed after such type of loading, as the result of which the fine grains are formed with subgrain refinement which takes place within the basis of alloy. It was found that overall plastic deformation of this alloy can be increased by a factor 2.75 compared with its initial state without significant loss of strength. Also we show that such process can be used as a preliminary microstructure refinement method for such alloy.
