Evolution of properties and composition of material powders in additive manufacturing

Eligibility: UK/EU/International

Award Details: £16,000 bursary plus tuition fees 

Duration: Full Time - 3 years 6 months fixed term

Application deadline: This opportunity will only remain open until a suitable candidate is identified- early application is therefore advised. Standard University research application closing dates apply http://www.coventry.ac.uk/research/research-students/application-dates/

Informal enquiries are essential before application; contact Dr. Michael Fitzpatrick to discuss this opportunity.

Congratulations on taking your first steps toward a Research Degree with Coventry’s Faculty of Engineering, Environment and Computing. As an ambitious and innovative University, we’re investing an initial £100m into our new research strategy, ‘Excellence with Impact’. Through original approaches from world-leading experts, we’re aiming for our research to make a tangible difference to the way we live. As a research student you are an integral part of Coventry’s lively and diverse research community and contribute to our reputation for excellence. With our exceptional facilities and superb support mechanisms you are afforded every opportunity for academic success.

The Project

A candidate is required for a research studentship in collaboration with NSIRC on assurance of powder quality in additive manufacturing (AM), primarily for powder that has passed through an AM machine to determine whether powder re-use is detrimental to the properties of the final component. 

The material quality in an additive manufactured part is critically dependent on the quality of the precursor powder used: alloying content; consistency within and between powder batches; and consistency of physical properties that will influence melting behaviour and possible subsequent segregation of alloying elements. A key question that has not been addressed is the re-use of powders. 

This programme will look at assurance of powder quality in AM, primarily for powder that has passed through an AM machine to determine whether powder re-use is detrimental to the properties of the final component. The experimental work will have three strands: (1) manufacture of test samples in different materials by re-use of powder over several iterations; (2) mechanical property characterization; (3) detailed characterisation of powders using state-of-the-art neutron and synchrotron X-ray methods.

Four materials will be studied: titanium alloy, aerospace aluminium, nickel-base alloy and austenitic steel. The test samples will have strength and ductility measured, to evaluate if there is a deterioration in properties as a consequence of the powder re-use. High-resolution diffraction can distinguish second phases even at these low volume fractions. For the alloys proposed, small-angle neutron scattering will be used. This comprehensive set of experiments of metallurgical characterisation coupled with mechanical property measurement will give a robust basis on which decisions can be made regarding development and assurance of protocols for re-use of powder in additive manufacturing techniques. 

Areas of study will include: high-resolution powder diffraction; the novel “total scattering” technique; and small-angle scattering to determine the degree of damage introduced into the powders by repeated passage through the AM machine.

About the Centres/Departments

Our research in Manufacturing and Materials Engineering builds on our historic research strengths at Coventry, and adds new research teams through investment and growth. It integrates seamlessly with the Institute for Advanced Manufacturing and Engineering, our flagship collaboration with Unipart Manufacturing.

This area of research will take a holistic approach to fabrication and manufacturing, focusing on the three strands of Materials, Processes, and Products; and underpinned by our expertise in Metrology and Advanced Experimentation.

We aim to be the research partner of choice for manufacturing industry in adding value, effecting knowledge transfer, generating intellectual property, and raising new technologies from concept up through the Manufacturing Readiness Levels.

Our summary research themes:

  • Process Control / Product Verification
  • Advanced Metrology and Experimentation
  • Supply Chain Management
  • Materials for Advanced Technologies
  • Integrated Product Enhancement

NSIRC is a state-of-the-art postgraduate engineering facility established and managed by structural integrity specialist TWI, working closely with top UK and International Universities and a number of leading industrial partners. NSIRC aims to deliver cutting edge research and highly qualified personnel to its key industrial partners.

Successful Applicants

Successful applicants will have:

  • A good first degree in Material Engineering, Physics or Mechanical Engineering with a minimum 60% mark in the Project element or equivalent with a minimum 60% overall module average, or
