摘要： The invention is related to the foundry practice. According to this invention, the method for making castings by directed solidification from a selected point of the melt toward the periphery of the casting comprises forming a casting in a mold having thermodynamic characteristics that allow uniform volume cooling of the melt to be effected to a temperature at which natural solidification processes are completed. To improve the structural isotropy of the casting formed, the cooling is effected at a rate not exceeding 0.5° C./sec. The casting is formed in a nonuniform field of force. The nonuniform field of force is set up by ultrasonic waves focused on a selected point of the melt to form therein a localized elevated pressure zone and to direct the solidification front from the zone toward the periphery of the casting. The nonuniform field of force is sustained in the mold until the cooling casting reaches a temperature at which the natural melt solidification processes are completed as the melt cools. Before the melt is poured into the mold, it is overheated to a level that, together with the thermodynamic characteristics of the mold allowing the melt therein to be cooled at a rate not exceeding 0.5 K/sec, sustains the liquid phase of the melt for a time sufficient for directed melt solidification to be effected from the selected point of the melt toward the periphery of the casting before the commencement of natural melt solidification processes as the melt cools. Subsequently, as the temperature at which natural solidification processes are completed is reached, the nonuniform field of force is removed, and casting cooling may continue at any reasonable rate.

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 creep and oxidation resistance substantially equivalent to or better than 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 method includes providing a mold including a molten casting material, moving the mold in a first direction, and guiding a solidification interface across the mold in a second direction in response to the moving the mold. The second direction is deviated from the first direction, and the solidification interface includes a transition to a negative heat transfer region. The mold moves in the first direction at a constant speed, and the mold includes heat transfer features such that a solidification time of the molten casting material at the conditions of the solidification interface is approximately constant as a function of the second direction.

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.

摘要： In the casting of a single crystal component, such as a turbine blade, by the lost wax casting technique, one or more ceramic pieces are positioned on a wax pattern at locations corresponding to parts of the cast component where relatively quick solidification of molten metal may occur during casting. A coating is subsequently formed around the wax pattern to define a mould, whereupon the wax is removed to leave the one or more ceramic pieces within the formed mould.
