Abstract:

The nanohardness of submicrocrystalline aluminum alloys produced by dynamic channel angular pressing has been measured. It has been shown that the nanohardness of the severely deformed material depends on the characteristics of its structural state. Grain refinement and changes in the density of dislocations have an ambiguous effect on the nanohardness of the alloys. The nanohardness variation is explained based on the current views on the mechanisms of the severe plastic deformation of alloys.
