Abstract

Liquid-solid ferrous compositions containing up to about 85 weight percent degenerate dendrites by vigorously agitating a partially solidified ferrous composition in an agitation zone to form degenerate dendrites while preventing the formation of interconnected dendritic networks. The interior surface of the agitation zone and the agitator is formed of high density recrystallized aluminum which remains stable against degradation by the partially molten ferrous composition and is not wet by the ferrous composition. An inert or protective gas blanket is maintained at the outlet of the agitation zone to prevent oxidation and slag formation thereby to prevent clogging of the outlet.
