The self-similarity theory of high pressure torsion [PDF]
Beilstein Journal of Nanotechnology, 2016 By analyzing the problem of high pressure torsion (HPT) in the rigid plastic formulation, we show that the power hardening law of plastically deformed materials leads to self-similarity of HPT, admitting a simple mathematical description of the process ...

Texture evolution in high-pressure torsion processing [PDF]
Progress in Materials Science, 2022 Abstract Among the severe plastic deformation processing (SPD) of materials, high-pressure torsion (HPT) is known to induce considerable amounts of plastic strain and crucial grain refinement up to the nanometer scale. There have been several reviews on the mechanical properties and/or microstructure correlations of SPD-processed materials published ...

High-pressure torsion of hafnium [PDF]
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2010 Abstract Pure Hf (99.99%) is processed by high-pressure torsion (HPT) under pressures of 4 and 30 GPa to form an ultrafine-grained structure with a gain size of ∼180 nm. X-ray diffraction analysis shows that, unlike Ti and Zr, no ω phase formation is detected after HPT processing even under a pressure of 30 GPa.

On nanostructured molybdenum-copper composites produced by high-pressure torsion. [PDF]
J Mater Sci, 2017 Nano-structured molybdenum-copper composites have been produced through severe plastic deformation of liquid-metal infiltrated Cu30Mo70 and Cu50Mo50 (wt.%) starting materials. Processing was carried out using high pressure torsion at room temperature with no subsequent sintering treatment, producing a porosity-free, ultrafine grained composite ...
