Evolution of Structure and Phase Composition of Aluminum Alloy under Severe Plastic Deformation

Abstract:

The paper shows that high thermal stability of the ultrafine-grained structure of aluminum alloy produced by severe plastic deformation is related to S-phase particles. The sequence of phase transformations of zirconium-doped ultrafine-grained alloy Al-Mg-Li in heating is revealed. The paper also determines temperatures at which depending on crystal structure two types of S-phase particles can form.
