Refinement of Boride by Rapid Solidification in Boronated Stainless Steel

Boronated stainless steel containing up to 2 mass%B, which is used for storage and transportation of spent nuclear fuel, has been well known as a poor workable material with large volume fraction of coarsely dispersed plate-like borides.Rapid solidification processes were applied to boronated stainless steels for refining borides and improving ductility and toughness.Borides were a little refined by the casting process using a water-cooled Cu...
