The diffusivity of indium as an impurity along grain boundaries in nickel bicrystals of known orientation has been measured using secondary ion mass spectrometry ISIMS). The values obtained are very large and comparable in magmtude to those observed by Hillert and Purdy. and by Smidoda. Gottschalk a
## Abstract Diffusion measurements of metallic and semiconductor melts on earth show highly irreproducible results due to occurrence of unknown convection. Therefore we investigated the influence of different kinds of additional transports. Diffusion experiments with the shear cell technique and nu
