(GIST OF SCIENCE REPORTER) Critical Near Isothermal Forging Technology

Defence Research and Development Organisation (DRDO) has established the near isothermal forging technology to produce all the five stages of High-Pressure Compressors (HPC) discs out of difficult-to-deform titanium alloy using its unique 2000 MT isothermal forge press.

The technology has been developed by the Defence Metallurgical Research Laboratory (DMRL), a premier metallurgical laboratory of DRDO at Hyderabad.
This is a crucial technology for establishing self-reliance in aero-engine technology. With this development, India has joined the league of limited global engine developers to have the manufacturing capabilities of such critical aero-engine components.
DMRL developed this forging technology by integrating various science and knowledge-based tools. The methodology adopted by DMRL is generic in nature and can be tuned to develop other similar aero-engine components.
The compressor discs produced using this methodology met all the requirements stipulated by the airworthiness agencies for the desired application.
