As with all the labs of DRDO, DMRL started its operations as a part of the [[Ordnance Factory Board]] at its Metal & Steel Factory in Calcutta in the year 1951 as the Technical Development Establishment (Metals), later to be upgraded as DMRL in 1956.<ref>http://ofbindia.gov.in/units/index.php?unit=msf&page=about&lang=en</ref> DMRL was shifted to Hyderabad in 1963. Since then, it has developed competence in the areas of powder metallurgy based fabrication and development of alloys, armor and rocket motor steel, aerospace light alloys, and magnetic materials. The formation of other entities such as the Mishra Dhatu Nigam Ltd., Heavy Alloy Penetrator Plant, Composites Production Centre, Non-Ferrous Technology Development Centre, and the Advanced Research Centre International have followed the establishment of DMRL. The DMRL is also involved in [[R&D]] efforts to develop futuristic materials to provide advanced technology options.<ref name=nti/> | As with all the labs of DRDO, DMRL started its operations as a part of the [[Ordnance Factory Board]] at its Metal & Steel Factory in Calcutta in the year 1951 as the Technical Development Establishment (Metals), later to be upgraded as DMRL in 1956.<ref>http://ofbindia.gov.in/units/index.php?unit=msf&page=about&lang=en</ref> DMRL was shifted to Hyderabad in 1963.
