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.

摘要： Casting molds (10, 56) suitable for directional solidification processes using a liquid cooling bath (60) include a graded facecoat structure (12) on a mold body (20). The graded facecoat structure (12) includes an innermost layer (14) and a delamination layer (18), wherein the delamination layer (18) fractures upon cooling of the molten metal so as to separate the mold body (20) from the innermost layer (14), which remains in contact with or in close proximity to the metal being cast. Also disclosed are directional solidification processes.

摘要： A system and method (80) for directionally casting an elongated device are provided. The method (80) includes orienting (82) a mold within a furnace such that a first portion of the mold points downward. The first portion of the mold defines a space within the mold used to form a first end of the device. The first end of the device, when formed, has a greater mass than a second end of the device. The method (80) also includes filling (84) the mold with molten metal and lowering (86) the mold out of the furnace into a liquid metal bath to immerse the first portion of the mold in the liquid metal bath. The method (80) includes concurrently lowering (88) the mold and the liquid metal bath to cool the molten metal.
