Abstract: A method of making a composite material consists of entraining finely divided solid additive particles in a stream of ionized inert gas and ionizing the inert gas and utilizing heat generated by the ionized gas to heat the solid particles to a high temperature which is less than the temperature in at which the solid particles become non-solid due to melting sublimination or dissociation. Then, injecting the stream of gas and entrained heated solid particles into a molten metal mass to provide a mixture of finely divided solid particles and molten metal and thereafter causing physical agitation of the mixture of molten metal and solid particles to establish a substantially uniform distribution of solid particles in the molten metal. Such physical agitation of molten metal is continued until the mixture of finely divided particles and metals is completely solidified.
