Abstract

Press bonding was carried out to study the bonding ability of superplastic 8090 aluminium alloy sheet in air. Surface roughness, deformation, time, and microstructure were the bonding variables chosen, to investigate the effects of these parameters on the bonding mechanisms. The mechanisms involved in press bonding to eliminate voids along the bond interface were instantaneous deformation on loading, plastic flow during heating, and a diffusion dominant mechanism. The contributions of the bonding mechanisms to the bonding effect were highly dependent on the original status of the specimens and the bonding variables. Plastic flow during heating was the major effect during bonding. The bonding effect response to time was related to the surface roughness and evolution of the microstructure during bonding. The effect of surface roughness on bonding depended on the bonding mechanisms.
