Abstract
The grain-boundary diffusion (GBD) of germanium in copper and its alloys Cu-2% Ge and Cu-0.5% Fe is investigated in the temperature range of 500–590°C by means of electron-probe microanalysis. The GBD parameters (triple product P = sδD GB and effective activation energy E) are found. The temperature dependence of the triple product for germanium GBD in pure copper can be described by equation P = 3 × 1015exp[−80 kJ mol−1/(RT)] m3 s−1. It is shown that the addition of Ge has almost no effect on the GBD parameters in copper, while do** with iron leads to a considerable reduction in the triple product.
