Through a combination of EPSRC and InnovateUK-funded projects the STAR group have successfully processed titanium powders into both wire and strip profiles on Continuous Rotary Extrusion (CRE) and Conform™ machines. This demonstrates the highly flexible nature of the process with both feedstock materials and machines.
We have used a multidisciplinary approach, implementing finite and discrete element modelling, lab-based powder experiments and time with CRE machines in order to fully understand the powder and material flow through the CRE process. The knowledge developed allows for rapid changes to machine running parameters and tooling to optimise the process for different powder and rod feedstocks.
We now have access to our own Conform™ machine at the University of Sheffield, accessed through the Henry Royce Institute, enabling further research on this process.
