Cryogenic grinding which cools materials to embrittle them and improve their processabiilty – provides important advantages over grinding at ambient temperatures particularly for materials that are too soft or too heat sensitive to be easily milled under routine conditions These advantages include The introduction of lower temperatures during cryomilling curbs recrystallization and embrittles materials so they can be fractured more easily with mechanical milling...
