摘要： Rhenium-free nickel based alloys are provided. More particularly, the alloys comprise preferred levels and ratios of elements so as to achieve good high temperature strength of both gamma matrix phase and gamma prime precipitates, as well as good environmental resistance, without using rhenium. When cast and directionally solidified into single crystal form, the alloys exhibit oxidation resistance better than or comparable to rhenium-bearing single-crystal alloys, and creep rupture life comparable to rhenium-bearing single-crystal alloys. Further, the alloys can be processed by directional solidification into articles in single crystal form or columnar structure comprising fine dendrite arm spacing, e.g., less than 400 μm, if need be, so that further improvements in mechanical properties in the articles can be seen.

摘要： A liquid metal cooled directional solidification process provides improved solidification characteristics at the solidification front. In the process, a mold is filled with molten metal; and a solidification interface is caused to pass through the molten metal by progressively immersing the mold into a cooling liquid. The cooling liquid is a eutectic or near eutectic metal composition. A directional solidification furnace includes a heating furnace, a liquid cooling bath and a mold positioner. The heating furnace has an open bottom end through which a heated mold containing molten metal is lowered from the furnace. The liquid cooling bath comprises a molten eutectic or near eutectic metal composition positioned beneath the open end of the furnace. The mold positioner gradually lowers the heated mold from the furnace, through the open end and immerses the mold into the liquid cooling bath.

摘要： A casting process and apparatus for producing directionally-solidified castings, and castings produced therewith. The process entails applying a facecoat slurry to a surface within a mold cavity to form a continuous solid facecoat on the surface, introducing a molten metal alloy into the mold cavity so that the molten metal alloy contacts the facecoat, and then immersing the mold in a liquid coolant to cool and solidify the molten metal alloy and form a casting of the metal alloy, during which an oxide layer forms on the casting surface. The facecoat is sufficiently adherent to the oxide layer such that at least a portion of the facecoat detaches from the mold surface and remains tightly adhered to the casting surface in the event the casting contracts during cooling. The facecoat contains at least 60 weight percent of a first phase of yttria, and the balance of the facecoat is a binder phase of an inorganic material.
