Biography:

2011-present: University of Cambridge, PhD in Materials Science, "Novel Refractory Metal Based High Temperature Alloys"

2007-2011: University of Oxford, MEng in Materials Science

Research Interests

Novel Alloys For High Temperature Service

Sandy's current work looks at the development of novel refractory metal based alloys for high temperature applications. Unusual alloy compositions are selected in order to generate microstructures capable of generating good elevated temperature mechanical properties whilst whilst also considering environmental protection. The alloys produced are targeted for high temperature applications, particularly for gas turbine engines, whilst also increasing the understanding of unusual systems with wider applications.

 

Particulate Reinforced Metal Matrix Composites

Previously, during his MEng final year research project, Sandy worked on powder processed aluminium metal matrix composites with ceramic nano-particle reinforcements.
