About the Project

This PhD project is sponsored by the Rutherford Appleton Laboratory (RAL) and the successful applicant will be based at the Materials and Engineering Research Institute at Sheffield Hallam University. The student will work closely with the industrial partner throughout the project.

The Supervisory Team will consist of:
Director of Studies: Dr Buddhadev Jana
Supervisors: Dr Yashodhan Purandare, Prof. Papken Hovsepian, Dr Arghya Dey (RAL)

Project Description:
The ISIS Neutron and Muon Source research centre based at RAL uses Ta-W source (target) to produce neutron pulses for neutron scattering experiments. During its operation the target is water cooled which is circulated at a high velocity causing erosion-corrosion damage and leading to a premature failure of the target material.

Erosion-corrosion is a type of wear process involving progressive loss of material due to combined wastage of mechanical action and chemical reactions. Erosion-corrosion studies of Ta-W materials have not been reported before and understanding of its erosion-corrosion performance is very limited. RAL is looking for innovative ways to improve the life of the target, improved tribo-corrosion resistance being the principal one.

The project will consist:
i) Conducting erosion-corrosion laboratory tests with the help of an impinging jet erosion-corrosion apparatus.
ii) Analysis of experimental results to identify material loss mechanisms using advanced analytical techniques and equipment in
iii) Analytical modelling to formulate a model to predict erosion-corrosion loss of Ta-W materials in the ISIS target station conditions, with a special emphasis on deriving a failure criterion based on the damage accumulation and material removal mechanism.

Funding Notes

The scholarship will cover the tuition fees (to Home/EU levels) and a Maintenance bursary at Research Council UK levels for three years of Full time study.

International applicants will be expected to contribute the difference between the Home/EU and International tuition fee levels.

The scholarship will commence in May 2019.
