Dislocation interactions during low-temperature plasticity of olivine strengthen the lithospheric mantle
David Wallis, Lars. N. Hansen, Kathryn M. Kumamoto +12
The strength of the lithosphere is typically modelled based on constitutive equations for steady-state flow. However, models of lithospheric flexure reveal differences in lithosphe…
Dislocation density distribution at slip band-grain boundary intersections
Yi Guo, David M. Collins, Edmund Tarleton +3
We study the mechanisms of slip transfer at a grain boundary, in titanium, using Differential Aperture X-ray Laue Micro-diffraction (DAXM). This 3D characterization tool enables me…
Low activation, refractory, high entropy alloys for nuclear applications
A Kareer, JC Waite, B Li +3
Two new, low activation high entropy alloys (HEAs) TiVZrTa and TiVCrTa are studied for use as in-core, structural nuclear materials for in-core nuclear applications. Low-activation…
Warren-Averbach line broadening analysis from a time of flight neutron diffractometer
David M. Collins, Angus J. Wilkinson, Richard I. Todd
The well known Warren-Averbach theory of diffraction line profile broadening is shown to be applicable to time of flight data obtained from a neutron spallation source. Without mod…
Pattern Matching Analysis of Electron Backscatter Diffraction Patterns for Pattern Centre, Crystal Orientation and Absolute Elastic Strain Determination: Accuracy and Precision Assessment
Tomohito Tanaka, Angus J. Wilkinson
Pattern matching between target electron backscatter patterns (EBSPs) and dynamically simulated EBSPs was used to determine the pattern centre (PC) and crystal orientation, using a…
Forescattered electron imaging of nanoparticles in a scanning electron microscopy
Junliang Liu, Sergio Lozano-Perez, Phani Karamched +3
In this study, we have used a Zr-Nb alloy containing well-defined nano-precipitates as a model material in which to study imaging contrast inversions (atomic number or diffraction…
