Solute strengthening is an important mechanism contributing to the strength of metallic alloys. In order to create an accurate framework for strength calculations, this mechanism must be fully understood. In that regard, studies have shown that it is crucial to include the core region of a dislocati...

To describe the behaviour of dislocations in solute strengthened alloys subjected to tri-axial stress states, it is important to understand how a superimposed hydrostatic pressure affects the dislocation-solute interaction. A pressure dependent yield strength has been experimentally observed by Spit...

Many important properties in the Al-Mg-Si alloy system, like hardness and toughness, is to a large extent determined by the atomistic precipitate interface structure. In this work we investigate the strain field around bulk hardening β'' precipitates and the fracture decohesion at β' grain boundary ...

A thermodynamic model is derived to study the void nucleation in ideal lattices under hydrostatic tension loading and predicts that the plasticity has to be initiated before homogeneous nucleation of voids. Molecular dynamics simulations are performed to evaluate the mechanical behavior of Ni specim...
