    When India’s indigenous aircraft carrier INS Vikrant II was officially launched in August, not many knew that the metal used in its making was developed by the city-based Defence Metallurgical Research Laboratory (DMRL).

    From supplying mundane aircraft brakes to developing technologies for flagship carriers, this former ‘inspection agency’ has come a long way. Take any indigenous project: helicopters, aircrafts, ships, tanks or missiles, this Defence Research and Development Organisation (DRDO) lab has left its indelible stamp, albeit an invisible one.

    Naval-grade steel DMR 249A, produced by the Steel Authority of India (SAIL) and used in INS Vikrant, was developed in close cooperation with the Indian Navy and other DRDO labs. Another variant, DMR 249B, which is used for underwater assets like submarines, is also ready and awaiting final certification, after which the Navy would not need to depend on importing special steel from Russia for its vessels, said DMRL Director Amol A. Gokhale.

    The lab has also successfully mastered a process to extract Titanium, a metal used extensively in aircraft production, from locally-available Ilmenite. The technology has also been transferred to the Kerala Minerals and Metals Limited for full-scale industrial production, Mr. Gokhale said, ahead of DMRL’s golden jubilee celebrations on October 26.

    A two-day seminar on Materials Technologies for Defence: Success Stories and Road Ahead is also being held on October 25 and 26, in which representatives from various DRDO labs, defence Public Sector Units, industry and academia will participate.

    The Mi-17-1V helicopter and the indigenous Arjun battle tank have been equipped with DMRL’s light-weight armour made of composite material.
