MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202611098131 A) filed by Indian Institute Of Technology Banaras Hindu University, Varanasi on August 13, 2026, for A Process For Preparation Of A Micro-Alloyed Steel Composition And A Product Thereof.
Inventors include Prashant Kumar Singh; Gautam Mishra; Jayant Kumar Singh; and Sudipta Patra.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention relates to a process for preparation of a micro-alloyed steel composition and a product thereof. The process of the present invention involves the controlled additions of vanadium, niobium, and nitrogen together with a specific thermal schedule comprising of austenitization at optimized temperature range, controlled cooling at a rate of approximately 15–20°C/s and intermediate-temperature isothermal holding and promotion of controlled interphase precipitation that collectively result in a refined ferritic microstructure containing nanoscale V(C,N)/Nb(C,N) precipitates, thereby achieving a favorable combination of yield strength and low-temperature toughness in heavy-gauge structural thick steel plates having thickness 50–100 mm.
