Ultrafine Grained Bulk 5083 Al Alloy Produced by Cryogenic Rolling Process


Article Preview

The large deformation at cryogenic temperature would be one of the effective methods to produce large bulk UFG materials. The effects of annealing temperature on microstructure and mechanical properties of the sheets received 85% reduction at cryogenic temperature were investigated for the annealing temperature of 150 ~ 300°C , in comparison with those at room temperature. Annealing of 5083 Al alloy deformed 85%, at 200°C for an hour, results in the considerable increase of tensile elongation without the great loss of strength and the occurrence of equiaxed grains less than 300nm in diameter.
