ARCI Introduces Advanced Technology for Machining Super-Alloys

Quick Summary

• Hyderabad-based ARCI (International Advanced Research Center for Powder Metallurgy and New Materials) unveiled a new machining technology for superalloys called Laser-Assisted Turning (LAT).
• LAT combines localized laser heating with mechanical cutting tools coated with tungsten carbide or CrAlSiN nanocomposites.
• The hybrid technique makes it possible to machine ultra-tough nickel-based superalloys like Inconel 625, commonly used in aerospace, nuclear, chemical industries, and power production systems.
• Challenges of machining superalloys typically include tool wear and inconsistent results due to their strength and heat resistance; LAT addresses these issues through thermal softening, reduced resistance during cutting, enhanced chip formation, and extended tool life.
• This breakthrough under DST’s Clean Coal Research Initiative offers scalable solutions for high-strength components in sectors such as aerospace,power generation,surgical tools manufacturing,turbine blades progress,marine engineering industries,etc.
