Investigation of the Substructure Evolution within Grains of Different Orientations during Recrystallization in a Commercial Al Alloy

Abstract:

In the present study, the substructure within grains of different orientations was investigated by means of EBSD technique. A 70% cold rolled commercial AA8079L alloy was annealed at two temperatures, 280°C and 320°C, for short times from 2 to 60 seconds. The subgrain size within the deformed grains of different orientations was measured. The results revealed no pronounced difference in subgrain size right after cold deformation. During further annealing at both investigated temperatures, Cube grains showed the highest recovery rate. It is concluded that the Cube oriented nuclei require an incubation time which is, obviously, much smaller than for grains of other orientations.
