Calderon, P D

An investigation was made of the diffusion bonding of 316 stainless steel to two types of Al alloys (6061 (T6 condition) and 1100 (0 condition)) and pure Al metal. A 0.05-mm (0.002-in.) thick silver interface applied by hot hollow cathode plating served as the joining medium. The tensile strengths of bond with all three Al alloys decreased after aging at 513K and 473K but not at 423K. Au-Al intermetallic compounds were formed. It was expected that aluminum alloying elements might play a role in either enhancing or retarding the growth of the intermetallic layer. The microprobe analysis results, however, did not support this expectation.
