Dr. Luke Benson-Marshall

Position:
Business Development Manager at Royce@Sheffield

I am a Post Doctoral Research Associate working towards low cost titanium components for use in automotive applications.

I studied both my MEng Materials Science and Engineering degree and my PhD in the Department of Material Science and Engineering at The University Of Sheffield. The title of my PhD thesis was “the influence of aluminium additions on titanium during machining through the application of a novel orthogonal cutting test method.

Current Research

My current primary research focusses on the development of novel low-cost titanium alloy chemistries derived from the Metalysis Process, formerly the FFC Cambridge Process, for processing using continuous rotary extrusion (CRE). This includes thermodynamic and kinetic modelling of candidate chemistries, development of powder compaction techniques and analysis, relevant extrusion practices and product property analysis and prediction.

Secondary research revolves around high performance machining of titanium alloys, which centres on the novel plain strain machining (PSM) test developed during the course of my PhD thesis. Areas investigated include cryogenic machining, ""machinable"" titanium alloy development predictions and subsurface deformation examination.
