摘要： In the casting of a single crystal component, such as a turbine blade, by the lost wax casting technique, one or more ceramic pieces are positioned on a wax pattern at locations corresponding to parts of the cast component where relatively quick solidification of molten metal may occur during casting. A coating is subsequently formed around the wax pattern to define a mould, whereupon the wax is removed to leave the one or more ceramic pieces within the formed mould.
