The influence of alloying on slip intermittency and the implications for dwell fatigue in titanium
Felicity F. Worsnop, Rachel E. Lim, Joel V. Bernier +5
Dwell fatigue, the reduction in fatigue life experienced by titanium alloys due to holds at stresses as low as 60% of yield, has been implicated in several uncontained jet engine f…
Precipitate dissolution during deformation induced twin thickening in a CoNi-base superalloy subject to creep
Vassili Vorontsov, Thomas McAuliffe, Mark C. Hardy +2
The tensile creep performance of a polycrystalline Co/Ni-base superalloy with a multimodal gamma prime distribution has been examined at 800C and 300MPa. The rupture life of the al…
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…
Effect of high temperature service on the complex through-wall microstructure of centrifugally cast HP40 reformer tube
Thibaut Dessolier, Thomas McAuliffe, Wouter J. Hamer +2
Centrifugally cast reformer tubes are used in petrochemical plants for hydrogen production. Due to the conditions of hydrogen production, reformer tubes are exposed to high tempera…
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…
Interface characteristics in an α+β titanium alloy
Abigail K. Ackerman, Vassili A. Vorontsov, Ioannis Bantounas +6
The alpha/beta interface in Ti-6Al-2Sn-4Zr-6Mo (Ti-6246) is investigated via centre of symmetry analysis, both as-grown and after 10% cold work. Semi-coherent interface steps are o…
