Strain field evolution on the surface of aluminum sheet D16 and 2024-T3 alloys has been analyzed during static deformation and during specific high-speed impact and oscillation loading-dynamical non-equilibrium process. Experiments have been conducted using an original mechanical testing technique and a specially developed software solution for noncontact study of strain field using digital image correlation fitted with a high-speed camera. It has been established that deformation process kinetics for tested aluminum alloys after a dynamical non-equilibrium process during further static deformation changes as compared with a process of static deformation mainly manifests itself in the increase in general alloy ductility and delay in ''neck formation.'' It has been shown that strain field is an important indicator for deformation band structure formation in the tested materials.
A simple technological method is proposed and tested experimentally, which allows for the improvement of mechanical properties in sheet two-phase high-strength titanium alloys VT23 and VT23M on the finished product (rolled metal), due to impact-oscillatory loading. Under impact-oscillatory loading and dynamic non-equilibrium processes (DNP) are realized in titanium alloys, leading to the self-organization of the structure. As a result, the mechanical properties of titanium alloys vary significantly with subsequent loading after the realization of DNP. In this study, the test modes are found, which can be used in the production conditions.
