Abstract: The present invention relates to a method of manufacturing of a casted part or ingot of a metallic alloy attaining a minimal segregation in the casting process, for alloys which are prone to segregate. The method can also be employed to refine the grain and microstructure of the obtained alloys. The method is especially interesting for Fe, Ti, Co or Ni based alloys. The method is very inexpensive and can be applied for the obtaining of very large cross-sections. An additional feature of the method is that it can be employed to capitalize impurities.
