4 year Engineering Doctorate (EngD): Machinability of Titanium AlloysSponsors: UoS / Sandvik Coromant / EPSRC
Start date: 4 September 2017
Stipend: £18,000 pa plus tuition fees paid at Home/EU rates
Sandvik Coromant are the world leader in cutting tools to the metals industry. To maintain our position, it is essential that we adapt and build our knowledge constantly to understand our customers’ latest processes and materials.
This EngD is to work with the workpiece materials team within Sandvik Coromant, to build our knowledge of machining titanium alloys. Specific topics that have been identified for further consideration are;
• Ti-5-5-5-3 machinability, in comparison with Ti-6Al-4V. Although there has been some academic research on this topic in the past, this has tended to focus on finishing processes, to minimise costs. This makes the work of questionable relevance to the roughing applications seen in industry. This should be considered in scoping this aspect further if it is selected for study.
• Machining of the alpha case in as forged Ti-6Al-4V components. This should include an analysis of the extent to which alpha case is formed in near net shape components, and the implications that this will have on the finishing process.
• Dry drilling of Ti-6Al-4V
These initial studies would be a mixture of reviews of literature and experimental work.
Machinability of titanium alloys is a topic that has been widely examined in academic circles, but generally with a focus in Ti-6Al-4V based alloys produced through conventional processing routes. As new alloys have come into mainstream use, and as processing methods have changed towards near net and additive manufacture, we need to understand the implications of these changes. The way in which our customers use the tools may be different, but also the machinability knowledge of the actual materials structures may be incomplete.
