ABSTRACT:
An inert gas stream carries crystalline or amorphous phase particles which are blown at a metal melt puddle from the exterior of a crucible nozzle facing a contact surface of a continuously moving chill body and spaced slightly therefrom through which is forced a stream of molten metal. This effects homogeneous distribution of a high volume fraction of second phase particles momentarily within the melt into ribbon form prior to rapid solidification during movement away from the nozzle orifice without particle clumping. The particles may be preheated to prevent particle clumping.
