DRDO HAS INDIGENOUSLY DEVELOPED HIGH STRENGTH BETA TITANIUM ALLOY

DRDO HAS INDIGENOUSLY DEVELOPED HIGH STRENGTH BETA TITANIUM ALLOY

Context:

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

About Metastable Beta Titanium Alloy:

  • It has been developed by Defence Metallurgical Research Laboratory (DMRL), a Hyderabad based laboratory of DRDO.
  • In recent times, these alloys are already being used by many developed nations as a valuable substitute for the relatively heavier traditional Ni-Cr-Mo structural steels to achieve weight savings.
  • The astounding forgeability of high strength-to-weight ratio Ti-10V-2Fe-3Al alloy works with production of intricately configured components for aviation applications with potential for significant weight savings.
  • Some of the components which may be forged from this alloy include landing gear, slat/flap tracks and drop link in landing gear among several others.

Significance of Metastable Beta Titanium Alloy:

  • The high strength beta titanium alloys are one of a kind because of their higher strength, fatigue, ductility, and fracture toughness making them progressively appealing for aircraft structural applications.
  • Furthermore, their relatively lower lifetime cost is an effective trade-off to legitimize the utilization of this costly material in India as well.
