Definitions

the casting process is preferably carried out in a vacuum or an inert atmosphere.
the molten alloy is poured into the preheated mold 20, after which unidirectional solidification is initiated by withdrawing the base of the mold 20 and chill plate 24 downwardly at a fixed rate to a cooling zone (not shown), which may contain a liquid metal cooling bath or a vacuum or ambient or cooled air for radiation cooling.
the casting 32 grows epitaxially (for example, with the ⁇ 100> orientation) based on the crystalline structure and orientation of a small block of single-crystal seed material 28 at the base of the mold 20, from which a single crystal forms from a crystal selector 30.
the columnar single crystal becomes larger in the enlarged section of the cavity 22.
