In contrast, even if the unbounded regions are accounted for in the strength calculations, the effect of stress concentrations at the boundaries between unbounded and bonded regions is likely to be reduced strength and increased variation in the results. 4 Conclusions A statistical approach was taken to examine the effects of time, temperature, surface finish, and foil thickness on the concentration and strength of diffusion bonded joints of commercially pure nickel. All samples were fabricated with a Brass 260 foil interlayer.
