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.

Apparatus for casting metal filaments directly from the melt comprising, in combination; (a) a crucible which is constructed of thermally conductive material for holding a metal charge; (b) means for supplying heat to melt the metal charge contained in said crucible to form a melt of molten metal; (c) at least one cooling passage internal to said crucible for passing a cooling medium therethrough to provide a solidified layer of the melt for preventing interaction between the melt and said crucible; (d) a nozzle forming an integral part of said crucible and enclosing an insulating insert having a passage therethrough for ejection of a stream of molten metal, said passage having a diameter of between about 0.06 and 0.1 in.; (e) means for rapidly quenching the stream of molten metal; and (f) means for controlling the ejection of the molten metal.
