kryomilling
Kryomilling, commonly spelled cryomilling, is a milling technique conducted at cryogenic temperatures, typically using liquid nitrogen, to reduce materials while controlling heat generation and chemical changes. The process embrittles many ductile materials, enabling brittle fracture rather than plastic deformation, which can lead to finer powders, refined microstructures, and reduced oxidation during size reduction.
In practice, a cryogenic mill or a standard ball mill equipped with a cooling system is used.
The anticipated outcomes of kryomilling include ultrafine or nanostructured powders, improved dispersion of reinforcements in composites,
Safety and practical considerations are important. Kryomilling requires specialized equipment and handling of liquid nitrogen, which
