MUMBAI, India, Dec. 13 -- Intellectual Property India has published a patent application (202511024693 A) filed by Malaviya National Institute Of Technology, Jaipur, Rajasthan, on March 19, for 'a method for synthesizing ultrafine grained gamma titanium aluminide alloys.'
Inventor(s) include Nadakuduru, Vijay Navaratna; and Kishor, Verma Mrigesh Naval.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to method for synthesizing ultrafine grained gamma titanium aluminide alloys with the composition Ti-46Al-1B (atomic %) using a cost-effective canned induction sintering technique. The process involves mechanical alloying of 100 grams of elemental powders (Ti, Al, and B) in required proportions using a planetary ball mill (PM 100, Retsch, Germany) with 500 grams of balls (ball-to-powder ratio 5:1). Wet milling is performed using toluene as a process control agent. The mechanically alloyed powder is cold compacted, canned in a stainless steel can, and vacuum-evacuated. The canned compact is preheated to 300 25 C and then induction sintered at 900-1100 C for rapid densification. The final bulk alloy exhibits an ultrafine-grained structure, making it suitable to be used as a precursor for producing near-net/ net shapes which can be used in aerospace and automotive applications. The method minimizes oxygen pick-up, reduces processing costs, and enables near-net shape manufacturing, making it a viable alternative to conventional synthesis techniques."
