Crystallographic ordering of Al and Sn in α-Ti
Felicity F. Worsnop, Susannah L. M. Lea, Jan Ilavsky +2
Increasing attention is being paid to Ti(Al,Sn) precipitation from the phase of titanium alloys owing to its effect on slip band formation, localisation and the imp…
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…
Nanoindentation in multi-modal map combinations: A Correlative Approach to Local Mechanical Property Assessment
C. M. Magazzeni, H. M. Gardner, I. Howe +5
A method is presented for the registration and correlation of intrinsic property maps of materials, including data from nanoindentation hardness, Electron Back-Scattered Diffractio…
The Kinetics of Primary Alpha Plate Growth in Titanium Alloys
Abigail K Ackerman, Alexander J. Knowles, Hazel M. Gardner +8
The kinetics of primary alpha-Ti colony/Widmanstatten plate growth from the beta are examined, comparing model to experiment. The plate growth velocity depends sensitively both on…
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…
Characterizing solute hydrogen and hydrides in pure and alloyed titanium at the atomic scale
Yanhong Chang, Andrew J. Breen, Zahra Tarzimoghadam +16
Ti has a high affinity for hydrogen and is a typical hydride formers. Ti-hydride are brittle phases which probably cause premature failure of Ti-alloys. Here, we used atom probe to…
