ABSTRACT:
A method for producing a functionally gradient component, such a component having an outer layer of a first material, and an inner core of a second material, there being a gradual change in microstructure across the interface between the two materials, the method having particular application in producing a component formed from two or more aluminium alloys based on the aluminium-silicon (Al—Si) system, the method involving introducing a first molten metal into a mould, and allowing a layer of the first metal to partially solidify against a wall of the mould, decanting the remaining molten portion of the first metal, and introducing a second molten metal into the mould and allowing same to solidify.
