    Abstract: A syntactic metal foam composite that is substantially fully dense except for syntactic porosity is formed from a mixture of ceramic microballoons and matrix forming metal. The ceramic microballoons have a uniaxial crush strength and a much higher omniaxial crush strength. The mixture is continuously constrained while it is consolidated. The constraining force is less than the omniaxial crush strength. The substantially fully dense syntactic metal foam composite is then constrained and deformation worked at a substantially constant volume. The deformation working is typically performed at a yield strength that is adjusted by way of selecting a working temperature at which the yield strength is approximately less than the omniaxial crush strength of the included ceramic microballoons. This deformation causes at least work hardening and grain refinement in the matrix metal.

    Abstract: A method of forming a powder of a composite material is provided, each composite powder particle comprising both a matrix phase and a reinforcement phase distributed within the matrix phase. The method comprises the step of forming a precursor powder (190) with an average particle size of less than 150 micrometres, each precursor powder particle comprising a matrix precursor material and a reinforcement precursor material. The matrix precursor material comprises a reducible compound comprising a first metal and oxygen. The precursor powder is reduced under conditions in which oxygen is removed from the matrix precursor material, but in which the reinforcement precursor material does not react. Thus, the matrix phase of the composite comprises the first metal, and the reinforcement phase of the composite consists of the reinforcement precursor material. A precursor powder (190) and a powder of a composite material are also provided.
