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 ...

Diffusive and Displacive Phase Transformations in Nanocomposites under High Pressure Torsion [PDF]
Archives of Metallurgy and Materials, 2019 The high-pressure torsion (HPT) of Ti-Fe alloys with different iron content has been studied at 7 GPa, 5 anvil rotations and rotation speed of 1 rpm. The alloys have been annealed before HPT in such a way that they contained different amounts of α/α' and
