Arc-melting process for forming metallic-second phase composites |
摘要 |
An arc-melting method is taught for the formation of metallic-second phase composite materials. The method involves the formation of an intermediate composite material comprising a relatively high loading of second phase particles dispersed in a metal matrix. This intermediate material is then combined with an additional amount of metal and arc-melted to form a final composite comprising a lower loading of the second phase particles dispersed in a final metallic matrix. The final metallic matrix may be comprised of a metal, metal alloy, or intermetallic, while the second phase particles may comprise ceramic materials such as borides, carbides, nitrides, silicides, oxides or sulfides.
