摘要： Various braze alloy compositions are described, along with methods for using them. In one instance, a boron-free, high-temperature braze alloy includes selected amounts of chromium, hafnium, and nickel. The braze alloy can be used, for example, as a component in a wide gap braze mixture where a higher or lower melting point superalloy and/or brazing powder is used. The braze alloys may permit joining or repairing of superalloy articles with complex shapes, and may be used in high temperature applications. In some other braze alloy embodiments, a nickel- or cobalt-based braze composition can contain selected amounts of boron, but includes restricted amounts of chromium.

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

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 resistance substantially equivalent to 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.
