This directly measured values of diffusion coefficient is compared with the value obtained indirectly from the measurement of the Li-solute redistribution within the Al-3.5Li alloy solidified directionally in the Bridgman system. The adequate theoretical considerations dealing with the description of solute redistribution in eutectic system has been made to calculate the value of back-diffusion parameter for the performed 2D experiment. The definition of back-diffusion parameter has been rearranged to calculate the numerical value of the diffusion coefficient in the solid. It has been shown that back-diffusion parameter plays essential role in the model of solute redistribution which is discussed from the viewpoint of the application of current model for redistribution to calculation of the solidification path.}, type={Article}, title={Interpretation and Meaning of The Diffusion Coefficient in the Solid Al-3.5Li Alloy by Measurement of the Li-Solute Redistrib}, URL={http://czasopisma.pan.pl/Content/131860/PDF/10_METALLURGY_47_2_2002_Wolczynski_INTERPRETATION.pdf}, }
