DRDO develops high-strength beta Titanium alloy

A high strength titanium alloy has been developed by India’s Defence Research and Development Organisation (DRDO). This alloy has been developed for applications in aerospace structural forgings.


About the Titanium alloy

The titanium alloys are unique due to their ductility, higher strength, fracture toughness and fatigue which make them beneficial for various aircraft structural applications.

Also this alloy has relatively lower lifetime cost due to its superior corrosion resistance in comparison to steels, which makes it very beneficial for aircraft structural applications.

DRDO has said that this alloy can be used in various ways that include slat and flap tracks, landing gears and drop link in landing gear etc.

Over 15 steel components that can be replaced in the near future with this alloy have been identified by The Aeronautical Development Agency (ADA).


Composition of the alloy

This high strength alloy, Ti-10V-2Fe-3Al, contains Iron, Vanadium, and Aluminium. Defence Metallurgical Research Laboratory (DMRL) has developed this high strength Titanium alloy. The first component that was forged successfully by the ADA at HAL, with the DMRL’s involvement and duly certified for airworthiness was the landing gear drop link. This alloy’s excellent high strength-to-weight ratio forgeability has facilitated the manufacturing of the intricate components which are necessary in aerospace applications.
