BETA TITANIUM ALLOY

July 21, 2021

Defence Research and Development Organisation (DRDO) has indigenously developed a ‘High Strength Metastable Beta Titanium Alloy’ containing Vanadium, Iron and Aluminium, Ti-10V-2Fe-3Al (non-ferrous near-beta titanium alloy) on industrial scale for applications in aerospace structural forgings.

About:

  • It has been designed and developed by DRDO’s Hyderabad-based Defence Metallurgical Research Laboratory (DMRL).

  • The state-of-art alloys have been in use by many developed nations in recent times as a beneficial and cost-effective substitute for the relatively heavier traditional Ni-Cr-Mo structural steels to achieve weight savings.

  • The higher strength, ductility, fatigue, and fracture toughness of the titanium alloy can replace steel and can lead to considerable weight savings.

  • The components which may be forged from Beta Titanium Alloy include slat/flap tracks, landing gear, and drop link in landing gear among several others.
