On the dynamics of curved dislocation ensembles

István Groma, Péter Dusán Ispánovity, Thomas Hochrainer

To develop a dislocation-based statistical continuum theory of crystal plasticity is a major challenge of materials science.During the last two decades such a theory has been devel…

Length scales and scale-free dynamics of dislocations in dense solid solutions

Gábor Péterffy, Péter D. Ispánovity, Michael E. Foster +2

The fundamental interactions between an edge dislocation and a random solid solution are studied by analyzing dislocation line roughness profiles obtained from molecular dynamics s…

3D HR-EBSD characterization of the plastic zone around crack tips in tungsten single crystals at the micron scale

Szilvia Kalácska, Johannes Ast, Péter Dusán Ispánovity +2

High angular resolution electron backscatter diffraction (HR-EBSD) was coupled with focused ion beam (FIB) slicing to characterize the shape of the plastic zone in terms of geometr…

An efficient implicit method for discrete dislocation dynamics simulations

Gábor Péterffy, Péter Dusán Ispánovity

Plastic deformation of most crystalline materials is due to the motion of lattice dislocations. Therefore, the simulation of the interaction and dynamics of these defects has becom…

Investigation of geometrically necessary dislocation structures in compressed Cu micropillars by 3-dimensional HR-EBSD

Szilvia Kalácska, Zoltán Dankházi, Gyula Zilahi +4

Mechanical testing of micropillars is a field that involves new physics, as the behaviour of materials is non-deterministic at this scale. To better understand their deformation me…

Strain distribution in polycrystals: Theory and Application for Diffraction Experiments

Adam Takacs, Géza Tichy, Péter Dusán Ispánovity

Randomly textured polycrystalline materials of constituents with highly anisotropic nature of grains can be considered globally isotropic. In order to determine the isotropic prope…
