Towards standardisation of average grain size measurement of additively manufactured microstructures using EBSD
Vivian Tong, Hannah Zhang, Jacopo Del Gaudio +2
Additively manufactured (AM) alloys have heterogeneous microstructures with broad grain size distributions and highly anisotropic and/or non-convex grain shapes. AM components can…
Curvature-enhanced localised emission from dark states in wrinkled monolayer WSe2 at room temperature
Sebastian Wood, Filipe Richheimer, Tom Vincent +5
Localised emission from defect states in monolayer transition metal dichalcogenides is of great interest for optoelectronic and quantum device applications. Recent progress towards…
Micropillar compression of single crystal tungsten carbide, Part 1: temperature and orientation dependence of deformation behaviour
Helen Jones, Vivian Tong, Rajaprakash Ramachandramoorthy +3
Tungsten carbide cobalt hardmetals are commonly used as cutting tools subject to high operation temperature and pressures, where the mechanical performance of the tungsten carbide…
Micropillar compression of single crystal tungsten carbide, Part 2: Lattice rotation axis to identify deformation slip mechanisms
Vivian Tong, Helen Jones, Ken Mingard
The plastic deformation mechanisms of tungsten carbide at room and elevated temperatures influence the wear and fracture properties of WC-Co hardmetal composite materials. The rela…
In-situ study of creep in Sn-3Ag-0.5Cu solder
Tianhong Gu, Vivian Tong, Christopher M. Gourlay +1
The creep behaviour and microstructural evolution of a Sn-3Ag-0.5Cu wt.% sample with a columnar microstructure have been investigated through in-situ creep testing under constant s…
Understanding plasticity in zirconium using in-situ measurement of lattice rotations
Vivian Tong, Euan Wielewski, Ben Britton
Understanding deformation in polycrystalline metals is critical to use them in high-value high-risk applications. We present in-situ characterisation of plastic deformation of zirc…
TrueEBSD: correcting spatial distortions in electron backscatter diffraction maps
Vivian Tong, Thomas Benjamin Britton
Electron backscatter diffraction (EBSD) in the scanning electron microscope is routinely used for microstructural characterisation of polycrystalline materials. Maps of EBSD data a…
Rapid Electron Backscatter Diffraction Mapping: Painting by Numbers
Vivian S Tong, Alexander J Knowles, David Dye +1
Microstructure characterisation has been greatly enhanced through the use of electron backscatter diffraction (EBSD), where rich maps are generated through analysis of the crystal…
The effect of cooling rate and grain size on hydride formation in Zircaloy-4
Ruth Birch, Siyang Wang, Vivian Tong +1
We explore the distribution, morphology and structure of zirconium hydrides formed using different cooling rates through the solid state Zr+[H] --> Zr + hydride transus, in fine an…
Space rocks and optimising scanning electron channelling contrast
Ben Britton, Daniel Goran, Vivian Tong
Forescatter electron imaging is a popular microscopy technique, especially for scanning electron microscopes equipped with an electron backscatter diffraction detector. In principa…
AstroEBSD: exploring new space in pattern indexing with methods launched from an astronomical approach
Thomas Benjamin Britton, Vivian Tong, Jim Hickey +2
Electron backscatter diffraction (EBSD) is a technique used to measure crystallographic features in the scanning electron microscope. The technique is highly automated and readily…
Characterisation of slip and twinning in high rate deformed zirconium with electron backscatter diffraction
Vivian Tong, Euan Wielewski, Ben Britton
Zirconium alloys are used in the nuclear industry as structural materials, and can be subject to high strain rate loading conditions during forming and in the case of a reactor acc…
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…
