Microstructures and tensile properties of commercial purity aluminium alloy AA1235 under different annealing conditions

Microstructures, hardness, tensile properties and texture of cold-rolled AA1235 alloy are investigated under different annealing conditions. Precipitation of Al3Fe particles occurs during annealing of the alloy. These precipitates largely affect the microstructural behaviour, tensile properties and texture of the alloy. After complete recrystallization no change in mechanical properties is observed upon further annealing.
