Method for forming metal, ceramic or polymer compositions

摘要

Fine grain metal, ceramic or metal-ceramic or metal-polymer compositions are formed by impinging at least two liquid streams of metal, ceramic and/or polymer, upon each other to form a turbulent mixture having small eddies. At least a portion of the mixture is frozen quickly before grain and/or cell growth in the mixed components occurs to any substantial extent. The resultant product can be a solid or a slurry.
