Abstract
An apparatus for rapid solidification casting of molten high temperature and/or reactive metallic alloys has a heat extraction crucible for containing the alloy in liquid form. A nozzle forms an integral part of the crucible and allows for ejection of a stream of molten metal. The heat extracting crucible and nozzle are protected from the molten alloy by a shell of the alloy which has solidified and prevents reaction between the molten metal and the heat extracting crucible.
