Abstract : A method was developed for bonding stainless steel by means of in situ exothermic reactions, the products of which supply the metallic brazing material, the flux, and the major part of the heat required. Several exo-reactant compositions were evaluated as to their suitability for stainless steel bonding. An exo-reactant composition, designated SP, producing an 85-15 Ni-Mn braze alloy was selected for further development. The bonding of Rene 41 was investigated briefly. Indications are that fluxing and wet-ability is not a serious problem; however, exo-adhesives must be developed with ceramic and metallic phases with lower melting points than the SP composition developed in this investigation.
