Abstract
A method of furnace-less brazing of a substrate is provided. The method includes providing a substrate having a braze region thereon; disposing braze precursor material containing a nickel powder, an aluminum powder, and a platinum group metal powder on the braze region; and initiating an exothermic reaction of the braze precursor material such that the exothermic reaction produces a braze material that reaches a braze temperature above the solidus temperature of the braze material. A braze precursor material is also provided.

A method of furnace-less brazing of a substrate, comprising:
- providing a substrate having a brazing region thereon;
- disposing a braze precursor material containing an aluminum powder, a platinum group metal powder, and at least 18 atomic percentage of a nickel powder on the brazing region;
- and
- initiating an exothermic reaction of the braze precursor material such that the exothermic reaction produces a brazed material that reaches a braze temperature above a liquidus temperature for the brazed material.
