Evolution of the structure formation during dynamic pressing of the AMts alloy

Results of studies of phase and structural transformations in the aluminum AMts alloy (3003) during deformation by dynamic pressing are presented. Different schemes of loading material and their effect on the structure and properties of the alloy are considered. It has been found out that the formation of a submicrograin structure with a size of fragments of 400–600 nm is observed even after a single pass of the sample through two perpendicularly crossing channels upon increasing speed of the sample from 150 to 300 m/s. It has been found that the hardness of a submicrocrystalline alloy produced by dynamic pressing exceeds the hardness of a hot-pressed rod after subsequent cold-working by a factor of 1.5.
