Strengthening of edge prism dislocations in Mg-Zn by cross-core diffusion
The activation of prismatic slip in Mg and its alloys can be beneficial for deformation and forming. Experiments show that addition of Zn and Al solutes have a softening effect at/below room temperature, attributed to solutes facilitating basal-prism-basal ...

PERGAMON-ELSEVIER SCIENCE LTD2023Microscopic Digital Image Correlation Analysis of Strain Distributions in Stainless Steel 316L Induced by Multiaxial Cyclic Loading
Fatigue damage in materials results in localized strain at the microstructural level. In many engineering components of the cooling circuits of nuclear power plants, where austenitic steels are used, the material experiences multiaxial cyclic loading, eith ...
EPFL2023The influence of lattice misfit on screw and edge dislocation-controlled solid solution strengthening in Mo-Ti alloys
William Curtin, Carolina Baruffi, You Rao
Mo-Ti alloys form solid solutions over a wide range of compositions, with lattice misfit parameters increasing significantly with titanium content. This indicates a strong increase in the critical stress for edge dislocation motion. Here, we probe the tran ...
SPRINGERNATURE2023EBSD study of variant reorientation, texture, and twin formation in a martensitic NiTi alloy deformed in compression
Roland Logé, Cyril Cayron, Mathijs Pieter van der Meer, Junfeng Xiao
Martensitic crystallography plays a vital role in the texture evolution and mechanical properties in Nickel-Titanium (NiTi) shape memory alloys when subjected to deformation. However, their microstructural changes during deformation are not well known and ...
Oxford2023The effect of in-situ linear stress gradient on the frictional shear rupture growth in 2D

Deep heat mining requires activation of slip on pre-existing geological discontinuities and the creation of hydraulically conductive fracture networks. Fluid injection or diffusion of ground waters can rise the fluid pressure near pre-existing fractures an ...
2023Strengthening mechanisms in dilute and random solid solution high-entropy BCC alloys
Tuning the mechanical properties of metals, including strength, through adjusting the type and/or concentration of added solute elements, has been recognized as an effective way to design and produce materials with desired or optimized mechanical propertie ...
EPFL2022Machine learning for metallurgy IV: A neural network potential for Al-Cu-Mg and Al-Cu-Mg-Zn
William Curtin, Daniel John Gilles Marchand
Most metallurgical properties, e.g., dislocation propagation, precipitate formation, can only be fully understood atomistically but most phenomena and quantities of interest cannot be measured experimentally. Accurate simulation methods are essential but f ...

Roland Logé, Johann Michler, Xavier Maeder, Amit Sharma, Daniele Casari, Nicolò Maria Della Ventura
An SEM in situ uniaxial tensile testing setup allowing HR-EBSD acquisition during deformation was used to study the extension twinning mechanism in magnesium(Mg) at the micron scale. Structures were fabricated with two different crystal orientations, respe ...
ELSEVIER SCI LTD2021Theory of kink migration in dilute BCC alloys
William Curtin, Alireza Ghafarollahi
Plastic deformation in elemental BCC metals and dilute alloys is controlled by the slower of the kink pair nucleation and kink migration processes along screw dislocations. In alloys nucleation is facilitated and migration inhibited, leading to a concentra ...
