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.

Abstract: The present invention relates to metallurgy of non-ferrous metals and alloys and, more particularly, to a process for producing an aluminium-silicon alloy with a content of silicon of 2 to 22% by mass. The process comprises charging crystalline silicon onto the sole of a reverberatory furnace so that the charged crystalline silicon has a cone shape, casting liquid aluminium into the furnace bath at 780.degree.-820.degree. C. and agitation of the resulting aluminium-silicon melt by means of a shaped jet of the same melt; the melt jet is directed into the base of the cone of the charged crystalline silicon at a speed of the jet along the axis thereof of from 0.5 to 0.8 m/s; simultaneously with the beginning of agitation the melt temperature in the furnace bath is lowered to 670.degree.-750.degree. C. and agitation of the melt is effected at this temperature. The alloy can be used in the automobile industry, tractor manufacture in the production of consumer goods.
