摘要： A method of production of a component having at least one dimension that is more than 200 mm, said method comprising the steps of: a) providing a titanium aluminide melt; b) providing a cold sand casting mould; c) mounting the mould and the melt in a vacuum or inert atmosphere chamber; d) rotating the mould at a distance from a rotation axis to generate an artificial gravity in all parts of the mould of at least 30 g; e) pouring the melt along said axis of rotation into a gateway that leads the melt to a radius greater than a maximum radius of any part of the mould, the gateway being arranged to open into the mould in a direction contrary to that of said artificial gravity; f) wherein said pouring is at a speed that fills the mould in less than 5 seconds. The method is useful for the casting of long turbine airfoils used in electricity generation industry or large automotive turbocharger wheels.
