INDENTATION SIZE EFFECT IN HIGH PRESSURE TORSION PROCESSED HIGH ENTROPY ALLOY [PDF]
Acta Polytechnica CTU Proceedings, 2020 High entropy alloy HfNbTaTiZr in as cast conditions and after high pressure torsion straining was characterized by nanoindentation. The length-scale dependent material response (indentation size effect) was characterized by indentation at various ...

Cyclic high-pressure torsion of nickel and Armco iron [PDF]
Philosophical Magazine, 2006 Cyclic high pressure torsion, a modified version of High Pressure Torsion, is applied to Armco-iron and nickel. The results in terms of microstructure and flow stress are compared to samples deformed by conventional high pressure torsion. For both processes and both materials, a saturation in the decrease of the structure size and the increase in the ...

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 ...

The significance of slippage in processing by high-pressure torsion [PDF]
Scripta Materialia, 2009 Experiments were conducted to measure the extent of slippage occurring when thin disks are processed by high-pressure torsion. Separate tests were conducted on aluminum, copper and iron. The results show the extent of slippage varies between these three materials such that there is very little slippage in aluminum, slightly more slippage in copper and ...

In-Situ Synchrotron Profile Analysis after High-Pressure Torsion Deformation [PDF]
Crystals, 2019 The presence of hydrostatic pressure is a general crucial characteristic of severe plastic deformation methods for reaching high strains and for introducing large quantities of lattice defects, which are necessary to establish new grain boundaries ...

High-Pressure Torsion: A Path to Refractory High-Entropy Alloys from Elemental Powders
MetalsFor the first time, the refractory high-entropy alloys with equiatomic compositions, HfNbTaTiZr and HfNbTiZr, were synthesized directly from a blend of elemental powders through ten revolutions of high-pressure torsion (HPT) at room temperature.

Continuous high-pressure torsion [PDF]
Journal of Materials Science, 2010 Continuous high-pressure torsion (CHPT) was developed as an expeditious process to effect severe plastic deformation. Using the CHPT, sheets of high purity aluminum, copper, and iron were successfully processed by introducing intense shear strain under high pressure.
