Experiments were conducted on an Al-3 wt.% Mg-0.2 wt.% Sc alloy and pure Cu to evaluate the effect of high-pressure torsion (HPT). The results show that very substantial grain refinement is achieved in both materials with as-strained grain sizes of ∼150 and ∼140 nm, respectively. Microhardness measu
