The self-diffusion coefficients of nickel and chromium in nickel-chromium alloys containing 0 to 30 at% of chromium have been measured with a usual lathe sectioning technique. Polycrystalline specimens having 1 to 4 mm grain size were used. Measurements were carried out over the temperature range from 1040° to 1300°C. In all alloys examined, chromium atom diffuses more rapidly than nickel atom, and the ratio of diffusion coefficient of chromium to that of nickel is about 1.6 independent of the chromium content over the whole temperature range. Diffusion rates of both elements decrease slightly with the increasing content of chromium. The frequency factors for nickel self-diffusion are 1.9, 3.3, 1.6, and 2.9 cm2/sec, and the activation energies are 68.0, 70.2, 68.5, and 70.5 kcal/mol in alloys containing 0, 10.0, 19.9 and 29.7 at% chromium, respectively. For chromium, self-diffusion in respective alloys, the frequency factors are 1.1, 1.4, 1.9, and 3.2 cm2/sec, and the activation energies are 65.1, 66.5, 67.7 and 69.4 kcal/mol.
