In this method, a high-energy impact mill is used to continuously fragment andreweld powder particles as fresh internal surfaces are exposed. Frictional heating at theparticle interface causes local melting and consolidation, and rapid heat extraction bythe cooler particle interior causes rapid soli[r]
