Paper Title:
Interfacial Phenomena in Brazing of a Stainless Steel Face Sheet to a Honeycomb Core
  Abstract

One of the difficulties in manufacturing of sandwich honeycomb structures is the proper joining of honeycomb cores to face sheets. In this investigation, vacuum brazing process using BNi-2 brazing alloy was applied for these types of joints. Brazing cycles were performed at temperatures ranging from 1020 to 1050oC under different holding times ranging from 5 to 20 min. Three different zones were observed in the solidified braze layer. The width of each zone was altered by brazing cycle. The results showed the crucial role of boron element in the brazing alloy in wetting behavior and final products after brazing. The optimum brazing cycle was found to be 1020oC and 5 min holding time followed by heat treating the brazed samples at 600oC for 6 hrs.
