Defence Metallurgical Research Laboratory
Defence Metallurgical Research Laboratory (DMRL) is a research laboratory of the Defence Research and Development Organisation (DRDO). Located in Defence Research Complex, Kanchanbagh, Hyderabad. It is responsible for the development and manufacture of complex metals and materials required for modern warfare and weapon systems. History 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. 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.

OFE Copper
Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below. Specification Oxygen-free copper is typically specified according to the ASTM/ UNS database. The UNS database includes many different compositions of high conductivity electrical copper. Of these, three are widely used and two are considered oxygen-free: * C10100 – also known as ''oxygen-free electronic'' (OFE). This is a 99.99% pure copper with 0.0005% oxygen content. It achieves a minimum 101% IACS conductivity rating. This copper is finished to a final form in a carefully regulated, oxygen-free environment. Silver (Ag) is considered an impurity in the OFE chemical specification. This is also the most expensive of the three grades listed here. * C10200 – also known as ''oxygen-free'' (OF). While OF is considered oxygen-free, its conductivity rating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Materials Science Institutes
Material is a substance or mixture of substances that constitutes an object. Materials can be pure or impure, living or non-living matter. Materials can be classified on the basis of their physical and chemical properties, or on their geological origin or biological function. Materials science is the study of materials, their properties and their applications. Raw materials can be processed in different ways to influence their properties, by purification, shaping or the introduction of other materials. New materials can be produced from raw materials by synthesis. In industry, materials are inputs to manufacturing processes to produce products or more complex materials. Historical elements Materials chart the history of humanity. The system of the three prehistoric ages (Stone Age, Bronze Age, Iron Age) were succeeded by historical ages: steel age in the 19th century, polymer age in the middle of the following century (plastic age) and silicon age in the second half of the 20 ...

Beta-titanium
Titanium alloys are alloys that contain a mixture of titanium and other chemical elements. Such alloys have very high tensile strength and toughness (even at extreme temperatures). They are light in weight, have extraordinary corrosion resistance and the ability to withstand extreme temperatures. However, the high cost of both raw materials and processing limit their use to military applications, aircraft, spacecraft, bicycles, medical devices, jewelry, highly stressed components such as connecting rods on expensive sports cars and some premium sports equipment and consumer electronics. Although "commercially pure" titanium has acceptable mechanical properties and has been used for orthopedic and dental implants, for most applications titanium is alloyed with small amounts of aluminium and vanadium, typically 6% and 4% respectively, by weight. This mixture has a solid solubility which varies dramatically with temperature, allowing it to undergo precipitation strengthening. This ...

Arjun (tank)
The Arjun () is a third generation main battle tank developed by the Combat Vehicles Research and Development Establishment (CVRDE) of the Defence Research and Development Organisation (DRDO), for the Indian Army. The tank is named after Arjuna, the archer prince who is the main protagonist of the Indian epic poem ''Mahabharata''. Design work began in 1986 and was finished in 1996. The Arjun main battle tank entered service with the Indian Army in 2004. The 43rd Armoured Regiment, formed in 2009, was the first regiment to receive the Arjun. The Arjun features a 120 mm rifled main gun with indigenously developed armour-piercing fin-stabilized discarding-sabot ammunition, one PKT 7.62 mm coaxial machine gun and a NSVT 12.7 mm machine gun.

Kanchan Armour
The Kanchan Armour is the name informally given to a modular composite armour developed by India. The armour got its name from Kanchan Bagh, Hyderabad, Telangana, where the Defence Metallurgical Research Laboratory (DMRL) is located. Although the construction details of the armour remain a secret, it has been described as being made by sandwiching composite panels between rolled homogeneous armour (RHA). The number of layers may vary based on the user requirements. This armour is able to defeat armour-piercing discarding sabot (APDS) and high-explosive anti-tank warhead (HEAT) rounds and is known to defeat armour-piercing fin-stabilized discarding sabot (APFSDS).Kanchan armor frontierindia.net This armour is lightweight and compact.

Prithvi Missile
Prithvi (Sanskrit: ''"Earth"'') is a tactical surface-to-surface short-range ballistic missile (SRBM) developed by Defence Research and Development Organisation (DRDO) of India under the Integrated Guided Missile Development Program (IGMDP). It is deployed by India's Strategic Forces Command. Development and history The Government of India launched the Integrated Guided Missile Development Program in 1983 to achieve self-sufficiency in the development and production of wide range of ballistic missiles, surface-to-air missiles etc. Prithvi was the first missile to be developed under the program. DRDO attempted to build a surface-to-air missile under Project Devil. Variants make use of either liquid or both liquid and solid fuels. Developed as a battlefield missile, it could carry a nuclear warhead in its role as a tactical nuclear weapon. Variants The Prithvi missile project encompassed developing three variants for use by the Indian Army, Indian Air Force and the Indian ...
