behavior of silicon in the brazing clad sheet was studied. It is interesting to notice that the residue clad appears after the brazing process, regardless of the brazing conditions. Diffusion coefficients... probe microanalysis) scans at different locations along the cladding sheet and within the joint zone. Subsequently, the diffusion coefficients were used to predict the residue clad layer formation......
