Liquid argon quenching is a cryogenic technique utilized to rapidly cool materials, typically metals or alloys. By immersing the material in liquid argon at extremely low temperatures (-186°C), the atoms’ kinetic energy is significantly reduced, resulting in the formation of a fine-grained microstructure. This process enhances the material’s properties, such as toughness, strength, and wear resistance, making it suitable for applications in various industries, including aerospace, automotive, and electronics.
