Characteristics of iron and nickel diffusion in molten lead-bismuth eutectic

The characteristics of iron (Fe) and nickel (Ni) diffusion in molten lead-bismuth eutectic (LBE) were investigated experimentally by using capillary method. The diffusion coefficients of iron (Fe) and nickel (Ni) were determined from measured axial concentration distributions of Fe and Ni in LBE spe...
