摘要： A ceramic casting shell mold having a pre-selected shape is described. It includes alternate, repeating layers of a ceramic coating material and a ceramic stucco, defining a total thickness of the shell mold; and a ceramic-based mat of reinforcing material disposed in the alternate, repeating layers of coating material and stucco. The reinforcing material for the mat is usually made from a ceramic material, and includes fibers having a bi-directional orientation. A method for making a ceramic casting shell mold is also described, as well as articles cast from such a mold, e.g., superalloy articles.

摘要： A ceramic casting shell mold having a pre-selected shape is described. The shell mold comprises repeating layers of a ceramic material which define its wall thickness and shape. At least one of the layers of ceramic material contains refractory whiskers which provide structural reinforcement to the shell mold. The whiskers are usually incorporated into a layer of the ceramic material which is disposed at a position off-center of the wall-thickness of the mold. A method for making a ceramic casting shell mold is also described, as are metal- or metal alloy components cast in these shell molds.

摘要： A method for fabricating a fired ceramic article, a green product, and a fired ceramic article, all for use as a core in the investment casting of directionally solidified eutectic and superalloy material. A ceramic slurry is prepared of alumina, aluminum and a solution of a polymerizable binder in a liquid. The slurry is extruded under low pressure into a closed cavity to form a gelled green product which is subsequently heated in an oxygen-containing atmosphere, wherein the oxygen reacts with the aluminum in the green product to form alumina which advantageously causes an increase in volume of the green product which counters the shrinkage effects of heating. The polymerizable binder is of a type which cross-links with the alumina and upon heating the liquid component of such binder vaporizes and the remaining polymer component subsequently gasifies on further heating to leave desired interstitial pores within the green product, which assist in allowing the oxygen to permeate the green product, which assists in oxidation of the aluminum through the green product. The green product is thereafter sintered to form a substantially dimensionally precise ceramic article suitable for precision-casting of superalloy materials.

摘要： A heater that may include an outer housing and an inner tube is provided. The inner tube is in a coaxial relation to and within the outer housing. An inward facing surface of the inner tube defines a volume sufficient to receive a reaction capsule, and the outward facing surface is radially spaced from an inward facing surface of the outer housing sufficient to define a gap. A filler material is disposed within the gap. The filler material responds to pressure such that the filler volume is reduced by less than 5 volume percent at greater than 500 MPa pressure and at greater than 500° C. temperature. One or more heating elements are disposed in the gap. The heating elements are in thermal communication with the inner tube.
