24/04/18 - Post-Docs in Nuclear Engineering Meeting (PiNE) - Oxford, 6th and 7th September 2018

The 2018 Postdocs in Nuclear Engineering meeting will be held at the University of Oxford on Thursday 6th and Friday 7th September 2018. PINE offers the oppurtunity for post-doctoral or equivalent level researchers to get together in an informal environment, share their work and learn what else is going on in the nuclear research community. More experienced post-docs will give presentations giving overviews of areas of research that the UK currently is focusing on. Representatives from the nuclear industry and funding councils will be on hand to offer career advice and insights into the future of nuclear energy research in the UK.  A complimentary lunch and evening social is offered to registered participants, funded by Nuclear Champion grant and the UK Nuclear Data Network. Registered participants are encouraged to submit a poster abstract, of which the most intresting will be promoted into an oral presentation.

Registration is now live!!


23/03/18 - Microscopy of Irradiation Damage

Everyone's now gone home from what we think was a very successful meeting: 70 attendees, 13 invited talks, a huge number of posters in two lengthy and well-refreshed poster sessions, lots of time for discussion and two sociable dinners. All credit to Jack Haley for organising a great three days.

16/02/18 -  MAINTAiN grant awarded

The £1.2M Bristol-Oxford-Liverpool collaboarative project is led by Dr Mahmoud Mostafavi at Bristol: the Oxford part is being led by Ed Tarleton, with James Marrow, Alan Cocks and David Armstrong; with Karl Whittle at Liverpool.The project aims to provide a predictive model for creep deformation of in-core nuclear components in the presenceof irradiation damage.

23/01/18 - New Postdoctoral Vacancy

We are hoping to recruit a new Post Doctoral Research Assistant in Discrete Dislocation Dynamics; for further details please go to and search for vacancy 133783.  

01/10/17 - Ed Darnbrough joins MFFP team.

We're very pleased to welcome Ed Darnbrough as the new Postdoctoral Research Assistant in Characterisation of Radiation Damage. He will be working on a variety of research themes in microscopy, micromechanics and X-ray characteriation of nuclear materials.

20/9/17: David Armstrong appointed to  Associate Professorship in Materials

We are very pleased to be able to announce that David Armstrong, currently a RAEng Fellow in the department, has been appointed to the new Associate Professorship in Materials, jointly with Corpus Christi College, from 1st October 2017. David's pioneering work on developing and understanding micromechanical test methods is central to our work on fission and fusion materials. His research group now also works on novel materials for extreme environment applications and geological materials. David leads Oxford Materials' role in the CDT in fusion.

13/09/17 - Microscopy of Irradiation Damage: 21-23 March 2018

We are planning a small workshop-style meeting on “Microscopy of Irradiation Damage” in Oxford, 21st - 23rd March 2018. The meeting will be low cost, so as to encourage participation from active research students and postdocs. We expect that total numbers will be about 35-50 people. There will be ample time for discussions centred around a small number of “keynote” lectures and the substantial poster sessions where "work in progress" will be reported. More information.

08/09/17 - New Postdoctoral Vacancy

We are hoping to recruit a Postdoctoral Research Assistant in Characterisation of Radiation Damage. The appointment will be fixed term for up to 2 years.

Further information can be found here:

Vacancy Ref: 13014; Application Deadline: 12 noon, Thursday 28 September.

02/06/17 -  Materials under
Extreme Conditions Workshop

This half-day workshop wil take place in Oxford Materials' Hume-Rothery lecture theatre, on 7th July (Wed), from 13.30-18.00. Speaker will include David Armstrong (Oxford Materials) and Erica Lilleodden (Helmholtz-Zentrum Geesthacht).

25/04/17 - Fusion CDT highly rated in Mid-term Review

The Centre for Doctoral Training in Fusion, in which the Oxford MFFP group is a partner, has recently been reviewed by EPSRC. The outcome was very favourable. Some extracts from the assessment:

"Student recruitment is strong giving the CDT a large pool to choose from. The student cohort activities appear strong, with good cohort building and a useful pre-sessional module system that allows accepted students to prepare in advance of formally starting ..... Engagement with other fusion research institutions is excellent, both nationally and internationally. The provision of student training has been recognised as the best in Europe .... It is good to see that there is evidence of working with the nuclear fission CDTs, mostly in the materials area, organising a joint workshop."

20/04/17 - Felix Hofmann's and Ed Tarleton's work on FIB damage in Oxford University News

'The research shows that FIB beams have much further-reaching consequences than first thought, and that the structural damage caused is considerable. It affects the entire sample, fundamentally changing the material. Given the role FIB has come to play in science and technology, there is an urgent need to develop new strategies to properly understand the effects of FIB damage and how it might be controlled.'

21/12/16 - Sequential nucleation of phases in a 17-4PH steel

Guma Yeli, Maria Auger, Paul Bagot, George Smith and Michael Moody in the Atom probe tomography group of the Department of Materials in collaboation with Keith Wilford in Rolls Royce have studied the microstructure and mechanical properties of 17-4PH steel under thermal ageing at 4800C and 5900C. The findings have been reported recently in Acta Materialia. For the first time, the sequential nucleation and growth of Cu-rich precipitates (CRPs), Nb-rich precipitates, Cr- rich precipitates and Mn, Ni Si (MNS) - rich phase has been characterized at the atomic scale. The precipitates that are initially nucleated have been found to act as favoured sites for heterogenous nucleation of subsequent phases. MNS phase precipitates were transformed from Nb-rich precipitates. This study also works to correlate the microstructure to the observed mechanical properties. The contributions of precipitates on the precipitation hardening has been estimated and compared with the Vickers hardness results.

10/10/16 - Quantifying yield behaviour in metals by X-ray nanotomography

James Marrow and Dave Armstrong, with colleagues from Bristol and Manchester, have used X-ray tomography and digital volume correlation in a unique study that measured the three-dimensional displacement field below a nano indentation. Their paper, published in Scientific Reports, addresses the problem that whilst it is possible to measure elastic properties and yield strength via nanoindentation, it is difficult to investigate strain hardening as the load-displacement data alone do not provide a unique solution for the material's plastic properties. The three-dimensional map of the displacements beneath the indentation provides additional information that overcomes this difficulty, so the strain hardening exponent can then be extracted using an inverse finite element simulation. The paper describes how the new analysis is applied to a nano- structured oxide dispersion strengthened steel, which has potential applications in advanced nuclear energy systems. They aim to study the plastic behaviour of proton irradiated steels in future work; protons simulate the effects of the fast neutron spectra of future nuclear energy systems, but only affect a shallow layer that may be investigated by nanoindentation.
