Structure and properties of ultrafine-grained aluminium alloys and possibilities of their application
Structure and properties of ultrafine-grained aluminium alloys, obtained by severe plastic deformation (SPD) and possibilities of their application have been considered. Two schemes of SPD as the most developed have been considered: high pressure torsion and equal channel angular pressing. SPD of aluminum alloys leads to grain refining down to nano-size. The structure has been characterized with high dislocation density, non-equilibrium grain boundaries and changed phase composition. The possibility of raising fatigue properties and demonstration of low-temperature and high strain rate superplasticity in extra strong ultrafine-grained aluminium alloys has been shown. Usage of SPD ultrafine-grained aluminium alloys is the most prospective as semi-finished product for follow formation in condition of superplasticity.
