Severe Plastic Deformation of Ceramics by High-Pressure Torsion: Review of Principles and Applications
Kaveh Edalati, Jacqueline Hidalgo-Jiménez, Thanh Tam Nguyen +8
Ceramics are typically brittle at ambient conditions due to their covalent or ionic bonding and limited dislocation activities. While plasticity, and occasionally superplasticity,…
Influence of nanostructuring through high-pressure torsion (HPT) on superconductivity of a high-entropy alloy
Kaveh Edalati, Alexy Bertrand, Payam Edalati +3
High-entropy alloys (HEAs) have emerged as favorable choices for different applications, including superconductors. The present work examines the impact of nanostructuring via high…
Significance of Strain Rate in Severe Plastic Deformation on Steady-State Microstructure and Strength
Kaveh Edalati, Qing Wang, Nariman A. Enikeev +3
The microstructure and mechanical properties of materials saturate to steady states after severe plastic deformation (SPD). Despite the well-known effect of temperature on the stea…
Plasticity of an extra-strong nanocrystalline stainless steel controlled by the "dislocation-segregation'' interaction
N. A. Enikeev, I. V. Lomakin, M. M. Abramova +4
We study three structurally different states of nanocrystalline 316 steel and show that the state, where boundaries containing excess concentration of alloying elements are combine…
Grain boundary segregation in UFG alloys processed by severe plastic deformation
Xavier Sauvage, Artur Ganeev, Yulia Ivanisenko +3
Grain boundary segregations were investigated by Atom Probe Tomography in an Al-Mg alloy, a carbon steel and Armco\trademark Fe processed by severe plastic deformation (SPD). In th…
On the origin of extremely high strength of ultrafine-grained Al alloys produced by severe plastic deformation
Ruslan Valiev, Nariman Enikeev, Maxim Murashkin +2
Ultrafine-grained Al alloys produced by high pressure torsion are found to exhibit a very high strength, considerably exceeding the Hall-Petch predictions for the ultrafine grains.…
