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.
In order to achieve this the EngD student will develop numerical models alongside experimental trials, the aims of which will be as follows:
• Examination of the current heat treatment process. Thermocouples will be located on the test coupon during its heat treatment to understand variation of temperature and location of the parts in the furnace.
• Analyse the impact of the stresses from other processes such as strengthening, machining and grinding, grit blasting and the HVOF process on distortions.
• Investigate methods to characterise residual stress and distortion data on these test coupons to validate the numerical models.
• The EngD will look into developing a set of protocols to be followed on producing right first time components.
• Examine the role of the required heat treatments as a contributing factor for the remaining residual stresses. The EngD will look into providing an insight of how the temperature does vary within the furnace and its impact on the hardened coupon; this will be qualified using residual stress and thermocouple data.
• Understand the individual impact on the induced residual stress within the component due to machining, straightening, grit blasting/ surface coating on the variability of the part distortions.
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.
The other challenge is the lack of understanding of the individual impact of the induced residual stresses due to machining, straightening, grit blasting or hardening process have on the variability of the part distortions.
Candidates must also be able to 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).

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, materials science, maths or physics, and be willing to get involved in hands-on activities. You should be enthusiastic about research with an interest in technology development and innovation in manufacturing.
*Due to EPSRC residency requirements, this project is open only to UK / EU applicants who have been resident in the UK for at least 3 years immediately preceding the start of the course.
