High-speed deformation of metallic materials using channel angular pressing for producing an ultrafine-grained structure

The possibility of producing an ultrafine-grained structure of metals and alloys by dynamic channel angular pressing is discussed using titanium, copper, and aluminum-based alloys as an example. It is established that even one-pass deformation allows one to produce a submicrocrystalline structure with a grain size of 30–350 nm and to enhance the strength properties at a high retained plasticity.
