A method and system for forming a composite mixture of at least two materials, at least one of which is a metal or metal alloy. The materials in a molten state are supplied via inlet channels to a mixing region so as to indirectly impinge on each other and then to flow through an outlet channel to a cooling system, such as a casting or mold device or a device for providing rapid solidification thereof. The ratio of the cross-sectional area of the outlet channel to the sum of the cross-sectional areas of the inlet channels is arranged to be less than 32 and the ratio of the distance from the input side of the outlet channel to the input of the cooling system to the diameter of the outlet channel is arranged to be greater than 5.

A method of manufacturing dispersion-strengthened material wherein a first material having a metal matrix M and at least one metal X capable of reacting with boron is supplied in a molten state to a mixing region at a first velocity. A second material having a metal matrix M and boron is supplied to the mixing region at a second velocity. The materials impinge on one another to produce a reaction between the metal X and the boron to form a boride in the metal matrix M. The mixture is solidified and pulverized to a powder which is then cleaned and consolidated.

A technique for forming a composite mixture of materials, at least one of which is a metal, in which each of the materials is supplied in a molten or slurry state to separate channels. The materials are then supplied to one or more mixing regions substantially simultaneously where they are caused to impinge upon each other to form a composite mixture thereof. The composite mixture is supplied to one or more cooling regions for casting, the supplying of the materials to the separate channels, the forming of the composite mixture and the casting being performed in a substantially continuous operation.
