by grain boundary diffusion-inducedgrainboundarymigration is investigated by secondary neutral mass spectrometry depth profiling in Ag/Au and Ag/Pd nanocrystalline thin film systems. It is shown that the compositions in zones left behind the moving boundaries can be determined by this technique if
gradients developed by the diffusion processes itself.
