Nanoscale characterisation of hydrides and secondary phase particles in Zircaloy-4
Wenjun Lu, Paraskevas Kontis, Siyang Wang +4
The interaction of hydrogen and metals continues to be industrially relevant and is a critical part of creating and supporting a safety case for nuclear reactor operation. In the p…
Correlative statistical microstructural assessment of precipitates and their distribution, with simultaneous electron backscatter diffraction and energy dispersive X-ray spectroscopy
Chris Bilsland, Andrew Barrow, T. Ben Britton
Modern engineering alloys have bespoke microstructures, where features such as precipitates are used to control properties. In many Ni-based alloys, carbo-nitride precipitates are…
Effect of bed temperature on solute segregation and mechanical properties in Ti-6Al-4V produced by selective laser melting
S. Pedrazzini, M. E. Pek, A. K. Ackerman +11
Advanced characterisation techniques were used on LPBF Ti-6Al-4V samples produced on a heated base plate. When the substrate temperature is 100°C the elongation is 6\%, which incre…
High-angular resolution electron backscatter diffraction as a new tool for mapping lattice distortion in geological minerals
David Wallis, Lars N. Hansen, T. Ben Britton +1
Analysis of distortions of the crystal lattice within individual mineral grains is central to the investigation of microscale processes that control and record tectonic events. The…
New techniques for imaging and identifying defects in electron microscopy
Daniel S. Gianola, T. Ben Britton, Stefan Zaefferer
Defects in crystalline materials control the properties of materials, and their characterization focuses our strategies to optimize performance. Electron microscopy has served as t…
The role of β-titanium ligaments in the deformation of dual phase titanium alloys
Tea-Sung Jun, Xavier Maeder, Ayan Bhowmik +4
Multiphase titanium alloys are critical materials in high value engineering components, for instance in aero engines. Microstructural complexity is exploited through interface engi…
Microstructure and formation mechanisms of δ-hydrides in variable grain size Zircaloy-4 studied by electron backscatter diffraction
Siyang Wang, Finn Giuliani, T. Ben Britton
Microstructure and crystallography of δ phase hydrides in as-received fine grain and 'blocky' alpha large grain Zircaloy-4 (average grain size ~11 μm and >200 μm, respectively) wer…
Atomic scale analysis of grain boundary deuteride growth front in Zircaloy-4
A. J. Breen, I. Mouton, W. Lu +11
Zircaloy-4 (Zr-1.5%Sn-0.2%Fe-0.1%Cr wt. %) was electrochemically charged with deuterium to create deuterides and subsequently analysed with atom probe tomography and scanning trans…
Using transmission Kikuchi diffraction to characterise α variants in an α + β titanium alloy
Vivian Tong, Sudha Joseph, Abigail K. Ackerman +2
Two phase titanium alloys are important for high performance engineering components, such as aeroengine discs. The microstructures of these alloys are tailored during thermomechani…
