Determination of Intrinsic Diffusion Coefficients in Binary Alloys with Variable Molar Volume by the M-M Method

The Multiple-Marker (M-M) method is useful because it enables the determination of the intrinsic diffusion coefficients not only at the Kirkendall marker position but also at places where the M-M are located. However, the analysis is not applicable to the alloys with variable molar volume. In this work, a new graphical method that is applicable to the alloys with variable molar volume is proposed.
