Deformation behavior of submicrocrystalline aluminum alloys during dynamic loading

The structure and the mechanical properties of aluminum V95 and AMts alloys with various grain sizes (from micron to submicron) are studied in a wide range of strain rates (from 10^–3 to 10⁵ s^–1). Submicrocrystalline (200–600 nm) materials are formed by dynamic channel-angular pressing at a strain rate of 10⁵ s^–1 using a pulsed power source.
