Fully Funded PhD Scholarship: Microstructure Modification and Property Optimisation of IN713C Nickel Based Superalloy Produced via Investment Casting

Swansea University - Materials Engineering

This scholarship is funded by Cummins Turbo Technologies.

Start date: October 2018

Applications are invited to a 3-year fully funded PhD position in materials engineering. The project is funded and fully supported by Cummins Turbo Technologies to support their R&D material design activity for alloy property optimisation used in turbocharger wheel product. Cummins Inc. is the world's largest designer and manufacturer of diesel engines. Cummins' key markets for these engines are on-highway vehicles, industrial equipment, and power generation. Therefore, one of the major concern is cleaner, healthier and safer environment.

Cummins Turbo Technologies is located in Huddersfield, UK, which is the world's largest manufacturer of turbochargers for the medium-heavy duty diesel engines market and has a reputation for producing innovative and dependable solutions for specific product requirements of this key market sector. Cummins' priority is to improve engine efficiencies and emissions reduction in highway, marine and power generation applications and this leads the company to be involved directly in fundamental research activities in many universities here in the UK and worldwide. Although, the research work will be based in Materials Research Centre, College of Engineering, Swansea University, you will have an industrial supervisor at Cummins at Huddersfield and you will need to attend all regular and progress project meetings at the company. Throughout this project, the research activities will be mainly focused on the mechanical and microstructural characterisations of nickel-based superalloy used in turbocharger turbine wheels. The work includes investigation into structure/property relationship in the IN713C variant alloy using various micro-analytical tools including SEM, EDX, TEM and EBSD.

The successful candidate will assist and collaborate with the existing research team at Swansea University. The aim of the project is to develop a fundamental understanding of the exact correlations between chemical composition variation on phase stability, phase formation, precipitate size and shapes and their distribution in the IN713C microstructure produced via investment casting. Extensive heat treatment, ageing and mechanical testing will be conducted throughout this 3-year project in order to investigate the effect of overall/local material microstructure, microtexture and local/global texture on fatigue crack initiation/propagation during turbine wheel operation simulations at high temperatures.

Eligibility

Academic requirements:

Candidates should hold a degree with a minimum of an upper second (2.1) honours degree (or equivalent) in Engineering or Physical Sciences. No previous experience of mechanical testing and materials characterisation techniques are required.
