MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202631003713 A) filed by National Institute Of Technology, Rourkela, Orissa, on Jan. 14, for 'a tapered forging die, system and method for thermo-mechanical forging of face-centered cubic low-ductility alloys.'
Inventor(s) include Kumud Kant Mehta; Manojkumar S; and Yogesh Singh.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to a system and method for thermo-mechanical forging of low-ductility face-centered cubic (FCC) metallic alloys using a tapered forging die assembly (100). The die comprises four slightly inclined square forging surfaces converging toward a central vertex to initiate deformation at the billet center, reducing friction-induced undeformed zones, barreling, and forging loads. In the method, a heated billet is placed between a bottom tapered die (1) on the lower flat die (3) and an inverted top tapered die (2), a base of which contacts the upper flat die (4), and an initial height reduction of approximately one-third of the billet height is applied. This stage produces multi-axial compression and enhanced strain penetration. Subsequent deformation using flat dies yields a forged work piece (5) with improved dimensional accuracy, reduced barreling, refined microstructure, and superior mechanical properties compared to conventional flat-die forging."
