This post is part of the EPSRC grant ‘A moving cracking story: Designing against hydrgoen embrittlement in titanium,’ EP/T01041X/1 held by Prof Dye and Dr Gault. The grant aims to develop a series of titanium materials to examine the effects of phase composition and microstructure on hydrogen solubiltiy, hydride formation and hydrogen permeability (e.g. in a stress field) in titanium alloys, in order to understand how to design alloys that resist stress corrosion cracking. Key analytical techniques include HEDM, SAXS, cryo-FIB preparation, (S)TEM of titanium alloys and atom probe tomography, both at MPIE and Imperial College. The topic area is of interest in chemical plant and aerostructures, and especially in the fan and compressor sections of jet engines, e.g. for Rolls-Royce.
Duties and responsibilities
Key Responsibilities include:
- To produce samples of Ti alloys by casting, rolling and heat treatment, and to characterise their microstructures by optical and scanning electron microscopy.
- To examine hydrogen mobility, corrosion and stress corrosion cracking using, e.g. synchrotron X-ray diffraction, (S)TEM electron diffraction, electron backscattered diffraction and transmission Kikuchi diffraction.
- To develop and implement at Imperial College preparation routes that avoid the introduction of hydrogen, and validate these through the use of isotopic labelling (e.g. D).
- To develop world-leading expertise in the use of atom probe tomography or HEDM to characterise H-containing metallic materials.
- To develop towards research independence with a world-leading reputation in titanium alloys, their characterisation and performance in service.
- To liaise with other research staff and students working in broad areas of relevance to the research project
- To prepare results for publication and dissemination via journals and presentations.
- To attend progress and management meetings as required and network with other research groups, both those involved in the project, industrial collaborators and other groups world-wide.
- To attend relevant workshops and conferences as necessary.
- To develop contacts and research collaborations within the College and the wider community.
- To undertake instruction of PhD students, as agreed.
- To actively participate in Group research meetings and internal seminars.
