Abstract
An article that comprises a fine-grain, homogeneous microstructure is essentially oxide- and sulfide-free and segregation defect free. The article is produced by a process that comprises forming a source of clean refined metal that has oxides and sulfides refined out by electroslag refining; and forming the article by nucleated casting. The invention also sets forth the article made by a system for implementing the clean metal nucleated casting process.
