摘要:
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.
摘要(中):
包含细晶粒均匀微观结构的制品基本上是无氧化物和无硫化物,并且没有偏析。 该制品通过包括形成具有通过电渣精炼(1)精炼的氧化物和硫化物的清洁精炼金属源的方法来生产; 并通过有核铸造(2)成型制品。 本发明还提出了用于实施清洁金属成核铸造工艺的系统制成的制品。
