On nanostructured molybdenum-copper composites produced by high-pressure torsion. [PDF]

open access: yesJ 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]

open access: yesScripta 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 ...

Continuous high-pressure torsion [PDF]

open access: yesJournal 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.

Effect of Severe Plastic Deformation on Structure Refinement and Mechanical Properties of the Al-Zn-Mg-Fe-Ni Alloy

open access: yesMetals, 2021
This paper identifies the mechanisms of phase and structural transformations during severe plastic deformation by shearing under pressure (high-pressure torsion) of an Al-Zn-Mg-Fe-Ni-based aluminum alloy depending on different initial states of the ...

Microstructure and Hardness Evolution in Magnesium Processed by HPT [PDF]

open access: yesMaterials Research, 2017
High pressure torsion provides an opportunity to process materials with low formability such as magnesium at room temperature. The present work shows the microstructure evolution in commercially pure magnesium processed using a pressure of 6.0 GPa up to ...

INDENTATION SIZE EFFECT IN HIGH PRESSURE TORSION PROCESSED HIGH ENTROPY ALLOY

open access: yesActa 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 ...
