Breaks in the Hall-Petch Relationship after Severe Plastic Deformation of Magnesium, Aluminum, Copper, and Iron
Shivam Dangwal, Kaveh Edalati, Ruslan Z. Valiev +1
Strengthening by grain refinement via the Hall-Petch mechanism and softening by nanograin formation via the inverse Hall-Petch mechanism have been the subject of argument for decad…
Ab initio based analysis of grain boundary segregation in Al-Mg and Al-Zn binary alloys
M. V. Petrik, A. R. Kuznetsov, N. Enikeev +2
Based on ab-initio simulations, we report on the nature of principally different mechanisms for interaction of Mg and Zn atoms with grain boundaries in Al alloys leading to differe…
Modification of titanium and titanium dioxide surfaces by ion implantation: combined XPS and DFT study
D. W. Boukhvalov, D. M. Korotin, A. I. Efremov +7
The results of XPS measurements (core levels and valence bands) of P+, Ca+, P+Ca+ and Ca+P+ ion implanted (E=30 keV, D=1x1017 cm-2) commercially pure titanium (cp-Ti) and first-pri…
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…
Grain boundaries in ultrafine grained materials processed by severe plastic deformation and related phenomena
Xavier Sauvage, Gerhard Wilde, Sergiy Divinski +2
Grain boundaries in ultrafine grained (UFG) materials processed by severe plastic deformation (SPD) are often called "non-equilibrium" grain boundaries. Such boundaries are charact…
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.…
