Structural and chemical characteristics of grain boundaries (GB's) have been studied very intensely in recent years. Due to variations of these characteristics with GB orientation and with the misorientation of adjoining grains, it is desirable to investigate individual GB's with known orientation in well-characterized bicrystals. In this way, various GB properties of Fe-Si alloys were studied in a series of papers devoted to GB structure, segregation and intergranular corrosion. Another one of the phenomena that may contribute to the general understanding of GB structure is GB diffusion. Data on GB diffusion in Fe-Si model alloys were reported in several papers. For example, Teheux et al. measured the diffusivity of iron in polycrystals with varying Si content whereas Haynes and Smoluchowski studied an orientation dependence of Fe penetration depth in Fe-Si bicrystals and Shvindlerman et al. investigated Zn heterodiffusion in Fe-2.58 wt% Si bicrystal. The diffusion of iron in monocrystalline Fe-Si alloys has been studied. In the present work, the diffusion of iron isotope [sup 59]Fe was studied in a bicrystal of an Fe-1.82 wt.% Si alloy.
