摘要
The heterodiffusion coefficients of iron in nickel and cobalt, cobalt in nickel and iron, and nickel in cobalt and iron have been determined by electronic gauge microanalysis between 1136°C and 1370°C, at infinite dilution. The validity of this method is justified compared with some results obtained by radioactive tracers. The values obtained for frequency factors D0 and activation energies Q are found in table 8. The difference, ΔQ, between the heterodiffusion activation energies of transition impurity for a transition metal and the activation energy of matrix self-diffusion increases linearly with the atomic number of the impurity. ΔQ = αΔZ where α > 0 and ΔZ = Zsolute - Zsolvent. The analysis of the temperature dependence of correlation factor leads to a better determination for the vacancy-transition impurity interaction in a transition metal 1. (i). if Zsolute > Zsolvent; ΔQ > 0 (it is the case for DCo(Fe), DNi(Fe), DNi(Co)), then there is an impurity-vacancy repulsion and the correlation factor contribution can be neglected 2. (ii). if Zsolute < Zsolvent; ΔQ < 0 (it is the case for DFe(Co), DFe(Ni), DNi(CO)), then there is an impurity-vacancy attraction. © 1969.
