摘要：

A fundamental investigation of transport phenomena involved in the surface segregation in polycrystalline systems has been performed, studying a Fe-3.5at% Si bicrystal with one (001) and one (011) oriented surface, separated by an asymmetric grain boundary. The segregation kinetics of Si, P and S was investigated by means of AES (Auger electron spectroscopy). A combined mechanism of bulk diffusion and diffusion across the grain boundary was found to be responsible for the complex segregation behaviour.
