TL;DR: In this paper, an Al-1% Mg solid solution alloy with an annealed grain size of ~400μm was processed by high-pressure torsion (HPT) to produce a grain size with a high fraction of high-angle grain boundaries.

TL;DR: In this paper, the Zn-22% Al-Eutectoid Alloy and Pb-62% Sn eutectic Alloy were processed by high pressure torsion (HPT) over a range of experimental conditions.

TL;DR: Tantalum, a common refractory metal with body-centred cubic (BCC) crystalline structure, was processed by high-pressure torsion (HPT) at room temperature through different numbers of rotations as discussed by the authors.

TL;DR: In this paper, the superplastic behavior of an Al-12.7mass%Si−0.7 mass%Mg alloy was investigated under different conditions and a maximum elongation to failure of 379% was demonstrated with a strain rate sensitivity, m, of 0.52 and an activation energy for flow, Q, of 156.7 KJ/mol at 793 K at an initial strain rate of 1.67×10 −4 ǫs −1, which is close to the lattice diffusion activation energy of aluminum.

TL;DR: In this article, a commercial purity vanadium with an initial grain size of 27μm and a Vickers microhardness of Hv≈85 was processed by high pressure torsion (HPT) under a pressure of 6.0 GPa at room temperature through 1/2 to 10 turns.
