In order to measure the Kirkendall marker shift in a precise manner a new technique has been proposed. By the technique one can measure the marker shift as a distance between the Kirkendall marker position after annealing and the edge of the inert foil embedded in a diffusion couple parallel to the diffusion direction as it acts as an indicator for the initial marker position. Since the Kirkendall markers and the edge of the inert foil can bee seen in a sight of a microscope, the measurement is very easy and the accuracy of the data on the marker shifts is expected to be improved. The marker shifts in Cu–Sn alloys have been determined experimentally by this technique.
