Dislocation Interactions in Olivine Revealed by HR‐EBSD
TL;DR: In this paper, high-angular resolution electron backscatter diffraction (HR-EBSD) was applied to map geometrically necessary dislocation (GND) density, elastic strain, and residual stress in experimentally deformed single crystals of olivine.
Journal ArticleDOI
High temperature anelastic and viscoplastic deformation of fine-grained MgO-doped Al2O3
TL;DR: In this paper, anelastic and viscoplastic relaxation phenomena were observed, characterized by an activation enthalpy of 840 kJ/mol, and a stress-dependent component, activated above a threshold-stress amplitude of 2-4 MPa was found.

A consideration of cleavage in alpha titanium
TL;DR: In this article, two theories of cleavage fracture are considered for prediction of the cleavage planes and it is indicated that they do not explain cleavage on high index planes and no simple rationale will be possible, since theoretical studies will have to account for the influence of the embrittling species on the electronic band structure.

On Non-Glide Stresses and Their Influence on the Screw Dislocation Core in Body-Centred Cubic Metals II. The Core Structure
TL;DR: In this article, the change in core structure of the screw dislocation in a body-centred cubic lattice subjected to a general applied stress tensor is studied by means of computer simulation.

High temperature dislocation processes in precipitation hardened crystals investigated by a 3D discrete dislocation dynamics
TL;DR: In this article, 3D discrete dislocation dynamics is employed to investigate motion of general mixed dislocation segments subjected to high temperature loadings in microstructures with impenetrable particles.
