Abstract in another language

The microstructural and mechanical properties of a MnFeCoNiCu braze filler are analyzed and compared to a conventional nickel-based braze filler alloy on Haynes 214 as the base material. Tensile tests reveal that the samples brazed with the MnFeCoNiCu compositionally complex alloy (CCA) exhibit superior ductility increased by a factor of 1.6 compared to those brazed with the nickel-based filler. The ultimate tensile strength remains comparable (factor 1.03). Contact angles recorded during the brazing process indicate comparable wetting properties between the two fillers. Based on experimental investigations and Thermo–Calc predictions, improved brazing parameters are proposed for the CCA filler on Haynes 214. These recommendations include lower brazing temperatures, shortened holding times, and faster cooling rates.
