The creep behavior of 3003 aluminum alloy extrusions with various manganese contents in solid solution and different microstructures was investigated. Yield stress decreases with heat treatment time at 400°C both fibrous and recrystallized structures. These microstructures do not change during annealing. Specimen with high manganese contents in solid solution shows higher creep strength than that with low manganese contents even if yield stress are same at 200°C. Further, in the same manganese contents in solid solution, the specimen with the fibrous structure shows higher creep strength than the recrystallized one due to subgrain structure.
