A new spray forming technique has been developed to synthesise aluminium based metal matrix composites. In the present investigation, Al–2Mg–7TiO2 composite was successfully spray atomised and co-deposited on a rotating substrate. This paper describes the processing methodology for the fabrication of Al–TiO2 composites, which involves simultaneous introduction of aluminium melt and rutile particles through concentric tubes, followed by inert gas atomisation and deposition on a rotating copper substrate placed vertically below the atomiser at some predetermined height. Mechanical and physical properties of as-cast and mechanically worked composite materials are discussed. For comparison, Al–2Mg–5TiO2 composite was also prepared by stir cast method and characterised.
