| 摘要 |
A process for casting an exotic alloy in a metal mold comprising a relatively easily machined steel mold wherein the mold is prefabricated from component parts having those surfaces which are exposed to the cast metal being machined and finished by polishing. The mold formed is characterized by the unusually complex forms that are possible and is preferably removed partially by rough machining and the remainder being dissolved by an acid which will not attack the cast metal. The casting is recovered in a precise highly finished form requiring no further finishing process.
