An aluminium-2024 alloy was prepared in the annealed and the solution treated conditions. Specimens in both conditions were processed by high-pressure torsion (HPT) at temperatures of either 293 or 673 K giving grain sizes for both conditions of βΌ0.15 and βΌ0.30 m for these two processing temperature
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 βΌ150 and βΌ140 nm, respectively. Microhardness measu
An Al-3% Mg-0.2% Sc alloy was processed by high-pressure torsion (HPT) using samples in the form of solid disks and rings. Following HPT, all values of the measured Vickers microhardness fall onto a single curve when plotted against the equivalent strain, such that there are increasing values of har
