- Additional information
- Metastable beta titanium alloys (TWIP/TRIP) typically exhibit either low strength (200-500MPa) with high strain hardening and elongation, or higher strength but low strain hardening. Our new Ti-7Mo-3Cr alloy has both high yield strength (695MPa) and high work hardening rate (~1900MPa) and elongation (33.3%), owing to simultaneous {332}<113> and {112}<111> twinning validated by detailed transmission electron microscopy. The collaboration across Sheffield and Imperial College (EPSRC DARE EP/L025213/1) led to TIMET providing £50,000 of PhD funding to Knowles (Birmingham 2019-22) on Ti alloy development, and supported the Ti work package of Knowles’ Royal Academy of Engineering Research Fellowship (£500k).
