Two types of rapidly solidified filler alloys of nominal composition Cu-40Mn-10Ni (C50) and Ni-7Cr-3·2B-4·5Si-3Fe (N82) were used for stainless steel (SS304) brazing joints. The C50 foil is crystalline in nature, whereas N82 foil shows amorphous structure. The SS304/C50/SS304 joint shows solid solution phases at interfacial area, with maximum bond strength of 500 MPa, which qualifies to 80% of base metal strength. Conversely, the SS304/N82/SS304 joint develops brittle CrxBy intermetallic phases, which lowers bond strength to 330 MPa. © 2013 Institute of Materials, Minerals and Mining.
