METHOD AND MOLD FOR PREPARING CASTED SINGLE CRYSTAL |
摘要 |
A method and a mould for making a cast single crystal in which the casting mould comprises a main casting chamber and a seed crystal mounted at or adjacent the entry aperture to this chamber. The charge of molten metal is arranged to flow over the crystal to produce melting of its upper surface. The molten metal filling the mould is then arranged to solidify progressively from the seed crystal, which then imposes its own structure and orientation on the solidifying metal. |
