- A new material model is developed to predict temperature and strain-rate dependent plastic deformation of Ti alloys based on chemical composition and microstructural morphologies, eliminating the effects of processing history. Major hardening micro-mechanisms and microstructural evolution are embedded in the model and validated for a range of wrought and additively manufactured parts. The developed model successfully predicts flow strength of alloys produced by a wide range of primary operations such as machining and can be implemented to design alloys with the bespoke mechanical properties. This research led to a collaboration with the University of Cambridge and a follow-up publication.
