Abstract

The deformation and annealing behaviors of a 1050 Al alloy deformed at cryogenic temperature were investigated, focusing on the evolution of microstructures and mechanical properties. Especially, the effects of annealing temperature, $150~300^{\circ}C$, on microstructures and mechanical properties of the sheets received reduction of 88% at cryogenic temperature were investigated. The significant change in mechanical properties with the annealing temperatures of $200~300^{\circ}C$ would be attributed to the variations in the volume fraction of recrystallized grains and coarse equiaxed grains.
