The reaction zone width at the AISI 304L-brass interface is 8.3 μm, and at the interface between brass and Ti-6Al-4 V side, it is 12.4 μm for specimens processed at 825 ⁰C. The reason for the increased thickness of the reaction zone is because of higher bonding temperature, and annealing heat-treatment applied on the specimen.
