New titanium alloys have been developed for use in next-generation aircrafts by adding low-cost elements such as C, Fe, Al and Cr. Some of the newly developed alloys are Ti-4.5Al-2Mo-1.6V-0.5Fe-0.3Si-0.03C, referred to as KS Ti-9, and Ti-4.5Al-2.5Cr-1.2Fe-0.1C, referred to as KS Ti-531C. KS Ti-9 has been developed for rolled products, while KS-531C has been developed for extruded or forged products. The mechanical properties and microstructures of KS Ti-9 and KS-531C subjected to various thermomechanical treatments were investigated in order to achieve the best balance of strength and ductility.
