Abstract
A mould for use in manufacturing a single-crystal component by metal casting and epitaxial growth, includes a cavity in which the component is to be formed and a housing having an elliptical cross-section in which a single-crystal seed is disposed, the seed having an elliptical cross-section defined by a minor axis and by a major axis, the housing being in fluid communication with the cavity via an opening of circular cross-section through which molten metal is to flow, the single-crystal seed and the opening being centred on the same vertical axis, in which the minor axis and the major axis of the cross-section of the seed are oriented as a function of the secondary crystallographic orientations of the single-crystal forming the single-crystal seed.
