    This research was conducted by the application of high-pressure torsion (HPT) to Al-X wt pct Ag alloys (X = 5, 11, 20). Grain refinement was achieved to the size of ∼300 nm after HPT processing at room temperature. The aging behavior of the alloys after HPT processing was investigated using Vickers microhardness measurement, tensile testing, scanning electron microscopy, and transmission electron microscopy. This study confirms the dual effect of grain refinement and fine precipitation on the enhancement of the strength. It is also shown that at peak-aged condition, the tensile strength is enhanced while maintaining considerable ductility.
