Summary of Interests

My interests are focused upon enabling materials research at the nanoscale via the microscopy techniques of atom probe tomography (APT) and field ion microscopy (FIM). APT is a technique capable of material characterisations at the atomic-scale, in which each atom is identified chemically and located in three-dimensions with very high accuracy. Hence, it is a technique rapidly rising in prominence. The Atom Probe Group in the Department of Materials at the University of Oxford is interested and active in all areas of this research across a broad range of material systems.

In particular, I am developing a variety of new analytical techniques to improve the three dimensional reconstructions generated by APT and the subsequent atom-by-atom analysis of the resulting data.  I am interested in applying these techniques to the characterisation of a wide variety of systems to inform materials research projects.

Developing Atom Probe for 3D Atomic-Scale Imaging of Biomaterials
M. P. Moody / P. A. J. Bagot

Atom Probe Tomography (APT) underpins the research and development into a wide range of materials and devices. This 3D atom-by-atom imaging offers the exciting potential to provide truly unique insights to biomaterials research into materials such as teeth, bone, synthetic implant. However, the application to APT to the analysis of biomaterials can be extremely complicated. There are significant challenges to not only to undertake successful experiments, but also to maximise the quantity and accuracy of information that can be extracted from the data. In this project we will develop APT specimen preparation, experiment, 3D atom-by-atom image reconstruction and data analysis for reliable and routine characterisation of biomaterials in collaboration with our research partners at Imperial College and UCL.

Atom Probe Tomography of CERN and ITER superconducting wires
C Grovenor / M Moody

Some of the highest performing superconducting materials are now being developed for very high current applications in the magnets and power cables for large international machines for physics research (CERN) and for fusion demonstrators (ITER). These materials have extremely complex microstructures that are optimised for carrying very high currents in large magnetic fields, and controlling the elemental distributions at the nanaoscale is a vital part of the manufacturing process.  Atom Probe Tomography is the ideal technique to study these materials, but has not yet been much used in the optimisation in this field.  This project will allow the student to work closely with our collaborators in CERN and the USA to apply this technique to developing a better understanding of how the details of the manufacturing process influence the nanoscale chemistry and hence the superconducting properties of these materials.

Atomic-Scale Characterisation of Reactor Pressure Steels
M P Moody / P A J Bagot

The reactor pressure vessel (RPV) is a critical component of a nuclear fission reactor. Hence, the long-term stability, strength and toughness of RPV steels are of vital importance for the power-generating industry. The main experimental technique to be used will be atom probe tomography. This cutting edge microscopy technique enables a three-dimensional, atom-by-atom characterisation of the microstructure of the steel, providing unique insight into the fundamental mechanisms of solute clustering and the resulting embrittlement. Additional experimental work will involve complementary techniques such as focused ion beam, electron microscopy and mechanical property measurements. This is an ongoing collaboration between Oxford and Rolls Royce. The current ageing experiments will be continued with removal from furnaces and testing/examination of aged samples at suitable intervals. Current mechanistic understanding is that any nano-scale precipitation will be more likely found either on dislocations or grain boundaries. Because of this more emphasis will be placed on grain boundary behaviour and in particular the segregation of elements such as phosphorus, as well as Ni/Mn/Cu.
