There has been a notable progress in the development of new titanium alloys for non-aerospace applications in recent years particularly in US and Japan. Since the process steps required for the qualification of new alloys in non-aerospace applications is not as stringent as that for aerospace applications normally, the introduction of new alloys in non-aerospace applications is relatively easier and faster. This paper will review the recent progress in the development and the application of new titanium alloys primarily in automotive applications and introduce the characteristics and production experiences of the alloys. The alloys include TIMETAL 54M (Ti-5Al-4V-0.7Mo-0.5Fe) and TIMETAL Exhaust XT (Ti-0.25Fe-0.4Si). The advantages of new alloys over existing alloys and the potential for aerospace applications will be discussed.
