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 ...

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 ...

High-Pressure Torsion for Synthesis of High-Entropy Alloys [PDF]
Metals, 2021 High-pressure torsion (HPT) is widely used not only as a severe plastic deformation (SPD) method to produce ultrafine-grained metals but also as a mechanical alloying technique to synthesize different alloys.
