摘要： Methods for casting a metallic material to form a component are described. The component can be a superalloy-containing turbine part, for example. The general method includes the step of pouring the metallic material, in molten form, into an investment mold; and then rapidly immersing the entire investment mold into a bath that contains a low-melting liquid coolant metal, so as to achieve substantially uniform, multi-directional heat transfer out of the molten material. The molten material that solidifies to form the component is characterized by a fine-grained, equiaxed grain structure. Related embodiments include the use of two ingots that constitute the superalloy material. One ingot includes the oxygen-reactive elements, and is prepared by a vacuum-melting technique. The other ingot includes the remainder of the elements, and can be prepared by a number of techniques, such as air-melting processes.

摘要： An apparatus and method for casting an alloy using a unidirectional casting technique. The apparatus includes a mold adapted to contain a molten quantity of an alloy, a primary heating zone adapted to heat the mold and the molten alloy therein to a temperature above the liquidus temperature of the alloy, a cooling zone adapted to cool the mold and molten alloy therein to a temperature below the solidus temperature of the alloy and thereby yield the unidirectionally-solidified casting, and an insulation zone between the primary heating zone and the cooling zone. The apparatus also has a secondary heating zone separated from the insulation zone by the primary heating zone. The secondary heating zone maintains the mold and the molten alloy therein at a temperature below the liquidus temperature of the alloy. The temperatures within the primary and secondary heating zones are individually set and controlled.

摘要： A process capable of producing large metallic castings having lengths of one hundred centimeters or more and a unidirectional crystal structure substantially free of freckle defects. The process includes pouring a molten metal alloy into a preheated mold within a heating zone, withdrawing the mold from the heating zone, through a heat shield, and into a cooling zone to directionally solidify the molten metal alloy, and then cooling the mold to produce the casting and the unidirectional crystal structure thereof. The heat shield operates as a barrier to thermal radiation between the heating zone and the cooling zone, and the mold is withdrawn at a rate that, in combination with the heat shield, maintains a thermal gradient to solidify the molten metal alloy and form primary dendrite arms having an average spacing therebetween of about 150 to about 500 micrometers.

摘要： A process capable of producing large metallic castings having lengths of one hundred centimeters or more and a unidirectional crystal structure substantially free of freckle defects. The process includes preheating a mold within a heating zone of a directional casting apparatus, pouring a molten metal alloy into a cavity of the mold, and then withdrawing the mold from the heating zone, through a heat shield, and into a cooling zone of the directional casting apparatus to directionally solidify the molten metal alloy within the cavity. The heating and cooling zones establish an axial thermal gradient that defines a solidification front in the molten metal alloy within the cavity. The mold is withdrawn at a withdrawal rate that, in combination with the axial thermal gradient, causes the solidification front to be substantially flat and perpendicular to the withdrawal direction.
