Vacancy Information – Applications are invited for a fully funded 4-year EngD studentship covering UK fees and stipend /EU fees only, as part of The EPSRC sponsored AMRC Industrial Doctorate Centre (IDC).

A normal piston rod will follow twelve different operations starting off from a billet and finished off with grinding process. During the operations, the rod will be hardened, deep hole drilled, heat treated, machine turned and straightened if the part is out of the required tolerance and finally ground. During the processing of the rod, distortion issues are experienced and can vary from a few hundred microns to millimetres. The aim of this EngD is to develop a deeper understanding of the development and evolution of residual stress in the manufacturing process, and its effect on distortions in the parts in order to reduce the number of operations and to produce part in conformances.

The EngD will look into developing a set of protocols to be followed on producing right first time components for high L/D components. Currently, there is limited knowledge provides an insight on how the temperature varies within the furnace during hardening. The EngD will look into providing an insight of how the temperature does vary within the furnace and its impact on the hardened coupon qualified using residual stress and thermocouple data.

All applications should be submitted online. See the How to Apply section of the IDC in Machining Science website. Please follow the instructions carefully, and ensure that you specify which project you are applying for and include in your statement why you are interested in the project and how you will contribute.

Applicants must have, or expect to get, a 1st or good 2:1 degree (or Masters with Merit) in a relevant science or engineering subject such as Mechanical Engineering, Aerospace Engineering, Materials Science, or Physics.

Due to EPSRC residency requirements, this project is open only to UK and EU applicants who have been resident in the UK for at least 3 years immediately preceding the start of the course. Applicants must meet EPSRC eligibility requirements found here

Candidates must also be able show that their English language proficiency is at a level which allows them to successfully complete the EngD. All applicants require an English language qualification, typically a GCSE or an IELTS test (a score of 7 or above is required, with a minimum of 6 in each component).
