Abstract: In the present study, impulse pressure-assisted diffusion bonding of ferritic stainless steel was investigated. The effect of pressure pulsation and surface roughness on the tensile shear load-carrying capacity of the diffusion bonds was studied by evaluating the shear load and bond interface characteristics, and the optimum bonding parameters were determined. It was found that bond strength increases with the increase in maximum pulse pressure, and under optimum conditions, the failure occurred from the base metal in tensile shear testing. The void distribution analysis at the bond interface for some selected specimens was also done to study the effect of pressure pulsation. From FE-SEM observation, it was found that pressure pulsation helps in two ways: (a) it breaks the oxide film and (b) it fills the voids at the interface by plastic flow of the metal in the overlapped area. Also, pressure pulsation resulted in grain refinement at the interface owing to the compressive deformation, which led to the grain boundary diffusion. © 2018, Springer-Verlag London Ltd., part of Springer Nature.
