    摘要： Disclosed herein is a method comprising disposing a gel casting composition between an outer die and a wax pattern; wherein the wax pattern is a replica of a desired casting; reacting the gel casting composition to form a gel matrix; removing the wax pattern; extracting a solvent from the gel matrix to form a dried gel; and firing the dried gel to form a gel cast mold. Disclosed herein too is a method comprising disposing a gel casting composition between an outer die and a wax pattern; wherein the wax pattern is a replica of a turbine component; reacting the gel casting composition to form a gel matrix; removing the wax pattern; extracting a solvent from the gel matrix to form a dried gel; and firing the dried gel to form a gel cast mold.

    摘要： A nickel-based braze composition is described, containing nickel, palladium, and restricted amounts of boron and silicon. The composition can also contain tantalum, titanium, and zirconium, as well as aluminum, chromium, and cobalt. A method for joining two metal components, using the braze composition, is also described. The braze composition can also be used to fill cracks or other cavities in a component, e.g., a gas turbine part formed from a nickel-based superalloy. Articles of manufacture which contain the braze composition are also described.
