BRAZE MATERIALS AND PROCESSES THEREFOR
First Claim
1. A process, comprising:
- applying a braze material to a surface of at least a first substrate, the braze material comprisinga plurality of first particles of a metallic material having a melting point, anda plurality of second particles comprising at least one nonmetallic material chosen from the group consisting of oxides, carbides, and nitrides of at least one metal, the nonmetallic material of the second particles being more susceptible to heating by microwave radiation than the metallic material of the first particles, and the nonmetallic material being present in the braze material in an amount sufficient to enable the first particles to completely melt when the first and second particles are subjected to heating by microwave radiation;
heating the braze material with microwave radiation to sufficiently heat at least the second particles to cause the first particles to completely melt; and
thenallowing the molten first particles to cool, solidify, and form a solid brazement.

Abstract
Braze materials and processes for using braze materials, such as for use in the manufacturing, coating, repair, and build-up of superalloy components. The braze material contains a plurality of first particles of a metallic material having a melting point, and a plurality of second particles comprising at least one nonmetallic material chosen from the group consisting of oxides, carbides, and nitrides of at least one metal. The nonmetallic material is more susceptible to heating by microwave radiation than the metallic material of the first particles, and the nonmetallic material is present in the braze material in an amount sufficient to enable the first particles to completely melt when the first and second particles are subjected to heating by microwave radiation.
