Low temperature volume diffusion of zinc in aluminium

Study of diffusion mobility of Al−Zn solid solution

“…2 shows the calculated Arrhenius plot of the tracer diffusivity of Zn in the pure fcc-Al, to- gether with the experimental points, [15,16,19,[21][22][23]26,27,42,43] see the black markers therein. The fitted line reconciles very well with most of the experimental points.…”

“…Due to the limitation of the experimental technique, early studies were confined to relatively high temperatures, [15][16][17][18][19][20][21][22][23][24][25] whereas more recent efforts have extended measurements to lower temperatures. [26,27] References for the most relevant data are listed in Table 1 and include the experimental method, the data type, and the temperature range. It is apparent that the frequency factors and activation energies of the tracer diffusivity deduced from most of the listed resources roughly reconcile with each other over the entire range of temperature with the only exception being the work of Chatterjee and Fabian, [18] and this work was excluded from the assessment procedure.…”
