| abstract |
An active braze alloy composition is described, including nickel; or a combination of nickel and cobalt; about 2% by weight to about 30% by weight germanium; and about 1% by weight to about 5% by weight boron and about 0.5% by weight to about 5% by weight of at least active element. The composition is free of silicon. Braze alloy joints formed of the braze alloy composition, and located in various devices, structures, and machines, are also described. A related method for repairing a crack or other cavity within a metal component, using the braze composition, is further described. |
