TEM image simulations of overlapping phases - a case study of sheared β” precipitates in Al-Mg-Si alloys
Dislocation dynamic simulations of dislocation - precipitate interactions in 6xxx Aluminium alloys
Ab Initio Calculations of Dislocation Core Using a Cluster Model Approach
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...
Pressure Dependent Yielding in Solute Strengthened Aluminium - An Ab Initio Study
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...
Investigation of the energy pathway for generation of dislocations in silicon at Σ3 grain boundaries with the kinetic Activation-Relaxation Technique
Fundamental Studies of Precipitates as Strengthening Agents in Aluminium Alloys
Influence of precipitate interface structure on alloy properties in the Al-Mg-Si system
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 ...
Effect of amorphization-mediated plasticity on the hydrogen-void interaction in ideal lattices under hydrostatic tension
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...
