Mechanisms of Ti3Al precipitation in hcp alpha-Ti
Felicity F. Dear, Paraskevas Kontis, Baptiste Gault +3
Nucleation and growth of TiAl \textalpha{} ordered domains in \textalpha{}-Ti--Al--X alloys were characterised using a combination of transmission electron microscopy, atom…
AgCl-induced hot salt stress corrosion cracking in a titanium alloy
Yitong Shi, Sudha Joseph, Edward A. Saunders +4
The mechanism of AgCl-induced stress corrosion cracking of Ti-6246 was examined at \SI{500}{\mega\pascal} and \SI{380}{\celsius} for \SI{24}{\hour} exposures. SEM and STEM-EDX exam…
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…
Fatigue cracking in gamma titanium aluminide
Claire F Trant, Trevor C Lindley, Nigel Martin +2
Cast and HIP'ed \textgamma-TiAl 4522XD is being developed for use in jet engine low pressure turbine blades, where temperature variations occur through the flight cycle. The effect…
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…
4D-STEM elastic stress state characterisation of a TWIP steel nanotwin
T P McAuliffe, A K Ackerman, B H Savitzky +4
We measure the stress state in and around a deformation nanotwin in a twinning-induced plasticity (TWIP) steel. Using four-dimensional scanning transmission electron microscopy (4D…
