During the invention of jet engine, titanium has been immensely utilized in new alloys and production techniques to meet the standards for strength, creep resistance, metallurgical structure and high temperature. Through the processes like electron beam cold hearth melting and triple melting, high quality titanium metal alloys can be achieved. These alloys are further used in aerospace applications like airframes and engines.
Jet Engines- For rotating applications, titanium is used in jet engines. In the latest technological jet engines, wide chord fan blades made up of titanium increase the efficiency and reduce noise.
Airframes- Innovative alloys have replaced nickel alloys & steel in landing gear and nacelle applications. By using these substitutes, the airframe manufacturers are able to reduce weight and improve the efficiency of aircraft. Through forged slab, the aircraft plates & sheets are hot rolled. For making the plates for flat, vacuum creep flattering process is utilized. The diffusion bonding & superplastic forming have increased the usage of titanium alloy sheets in latest airframes' designs.
Aircraft strips, in beta alloys & commercially pure grades are manufactured in the form of coils along with consistent vacuum annealing which assure low hydrogen content. With the introduction of every new design, the manufacturers are increasing the usage of titanium in airframes.
