Tracer diffusion of 59Fe in 1.82wt%Si bicrystals with a symmetrical tilt {610} boundary was measured (tables 193 and 194) by using residual activity methods. It was found that the temperature dependence of the volume diffusion coefficients confirmed the magnetic anomaly of volume diffusion which had been reported for Fe diffusion in Fe-3.99wt%Si. The diffusion data were used to evaluate the grain boundary diffusion characteristics at temperatures of up to 1023K.
