摘要： An apparatus for countergravity casting a metallic material, comprises: a crucible for holding melted metallic material; a casting chamber for containing a mold; a fill tube capable of extending into the crucible to communicate melted metallic material to the casting chamber; a gas source coupled a headspace of the melting vessel to allow the gas source to pressurize said headspace to establish a pressure differential to force the melted metallic material upwardly through said fill tube into said mold; and means for gettering sulfur.

摘要： A method includes casting a metallic material (56) in a mold (20) containing a core, the core having a substrate (40, 44) coated with a coating (42). A removing of the metallic material from the mold and decoring leaves a casting having a layer formed by the coating. The coating has a ceramic having a porosity in a zone (50) near the substrate less than a porosity in a zone (52) away from the substrate.

摘要： A method casts a plurality of alloy parts in a mold (600; 700) having a plurality of part-forming cavities (601). The method comprises pouring a first alloy into the mold causing: the first alloy to branch into respective flows along respective first flowpaths (676, 684; 708) to the respective cavities; and a surface of the first alloy in the part-forming cavities to equilibrate. The method further comprises pouring a second alloy into the mold causing: the second alloy to branch into respective flows along respective second flowpaths (676, 680; 712) to the respective cavities.
