    Abstract: A ternary near eutectic alloy of Ni, Ti, Cr is described having a relatively low melting temperature of approximately 1230 deg. C. or less, suitable for fusing cracks in turbine blades and vanes without substantial risk of cracking during the repair process. Such an alloy is suitable for low temperature joining or repair of turbine blades since it contains the same components as typical turbine blades and vanes without foreign elements to lower the melting point of the repaired material or adversely affect the mechanical properties of the repaired component. Exclusion of boron eliminates the formation of brittle boron compounds, detrimental to the properties of the repair or seam.

  • Publication number: 20090159645
    Abstract: 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.
