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 applied to nickel single crystals [PDF]
Philosophical Magazine, 2008 Nickel single crystals with different crystallographic orientations were deformed by high pressure torsion. Special attention is devoted to the examination of micro-texture evolution and the development of the microstructure. The initial crystal orientation was found to have a significant effect on the hardening and evolution of micro-texture at low ...

Plastic yielding of glass in high‐pressure torsion apparatus [PDF]
International Journal of Applied Glass Science, 2018 Abstract Hardness measurements performed at room temperature have demonstrated that glass can flow under elevated pressure, whereas the effect of high pressure on glass rheology remains poorly quantitated. Here, we applied a high‐pressure torsion apparatus to deform SCHOTT SF6 ®

Using High-Pressure Torsion to Achieve Superplasticity in an AZ91 Magnesium Alloy
Metals, 2020 An AZ91 magnesium alloy (Mg-9%, Al-1% Zn) was processed by high-pressure torsion (HPT) after solution-heat treatment. Tensile tests were carried out at 423, 523, and 623 K in the strain rate range of 10−5−10−1 s−1 to evaluate the occurrence of ...
