Microstructural Evolution and Control of Aerospace and Automotive Alloys Using Selective Laser Melting and Electron Beam Melting
Supervisor: Dr K Mumtaz

The Additive Manufacturing (AM) technologies of Selective Laser Melting (SLM) and Electron Beam Melting (EBM) are used to produce fully functional metal components for aerospace, automotive and medical industries. Components are formed by completely melting thin layers of metal powder layer by layer. As a result of this additive approach microstructural control is limited. The ability to control microstructure during SLM/EBM will allow component performance to be further tailored and optimised for its function.

This project will investigate the thermal history of SLM/EBM high performance aerospace/automotive materials. Novel heating regimes and intelligent material selection is key in exerting control over microstructure. Materials will be processed under various processing conditions and an understanding of how specific microstructures evolve will be developed. Components will be mechanically tested and their performance compared to those built using conventional CNC machining/casting techniques.
