Effective structural unit analysis in hexagonal close packed alloys -- reconstruction of parent beta microstructures & crystal orientation post processing analysis
Ruth Birch, Thomas Benjamin Britton
Materials with an allotropic phase transformation can result in the formation of microstructures where grains have orientation relationships (ORs) determined by the transformation…
Quantitative precipitate classification and grain boundary property control in Co/Ni-base superalloys
Thomas P McAuliffe, Ioannis Bantounas, Lucy R Reynolds +4
A correlative approach is employed to simultaneously assess structure and chemistry of (carbide and boride) precipitates in a set of novel Co/Ni-base superalloys. Structure is deri…
Spherical-angular dark field imaging and sensitive microstructural phase clustering with unsupervised machine learning
Thomas P McAuliffe, David Dye, T Ben Britton
Electron backscatter diffraction is a widely used technique for nano- to micro-scale analysis of crystal structure and orientation. Backscatter patterns produced by an alloy solid…
Advancing characterisation with statistics from correlative electron diffraction and X-ray spectroscopy, in the scanning electron microscope
T. P. McAuliffe, A. Foden, C. Bilsland +3
The routine and unique determination of minor phases in microstructures is critical to materials science. In metallurgy alone, applications include alloy and process development an…
Gazing at crystal balls: Electron backscatter diffraction pattern analysis and cross correlation on the sphere
Ralf Hielscher, Felix Bartel, Thomas Benjamin Britton
We present spherical analysis of electron backscatter diffraction (EBSD) patterns with two new algorithms: (1) band localisation and band profile analysis using the spherical Radon…
Heterogeneous local plastic deformation of interstitial free steel revealed using in-situ tensile testing and high angular resolution electron backscatter diffraction
James L R Hickey, S Rouland, T B Britton
Metals are important structural materials for transport and the built environment. Low carbon steels can fail through strain localisation due to the role of interstitial solute ato…
