Context
The Defence Research and Development Organisation (DRDO) developed a high strength titanium alloy on an industrial scale for making aerospace structural forgings.
About the developed high strength titanium alloy
- The high strength metastable beta titanium alloy, Ti-10V-2Fe-3Al, contains Vanadium, Iron and Aluminium.
- It was developed by the Defence Metallurgical Research Laboratory (DMRL).
- The high strength beta titanium alloys are unique due to their higher strength, ductility, fatigue, and fracture toughness.
- It makes them increasingly attractive for aircraft structural applications.
- It has a relatively lower lifetime cost.
- It has superior corrosion resistance in comparison to steel.
- Some of the components which may be forged from this alloy include slat and flap tracks, landing gear and drop link in landing gear, among several others.
- It is a beneficial substitute for the relatively heavier traditional structural steel to achieve weight savings.
- The excellent forgeability of the high strength-to-weight ratio Ti-10V-2Fe-3Al alloy facilitated the manufacture of intricately configured components for aerospace applications with the potential for significant weight savings.
Titanium
- It is a chemical element with the symbol Ti and atomic number 22.
- Its atomic weight is 47.867 measured in daltons.
- It is a lustrous transition metal with a silver colour, low density, and high strength.
- Titanium is resistant to corrosion in seawater, aqua regia, and chlorine.
