Process for purifying metal compositions |
摘要 |
Purified metal compositions and metal compositions free of secondary phase material are produced by heating a metal alloy from the nonequilibrium solidus temperature while subjecting the liquid-solid mixture to high pressure and forcing the liquid through a filter. Compositions obtained by the process of this invention have a nondendritic structure which can be substantially free of secondary phase material.
