Abstract
The lattice diffusion coefficient of copper in high‐purity nickel single crystals is measured between 775° and 1050°C. The diffusion coefficient satisfies the equation D=0.27 exp(−61.02/RT) cm2 sec−1, with an error in D0 of ±22% and in Q of ±1%. A comparison with the results of other authors is given, showing that the dc measured is considerably lower than in previous investigations. This effect is referred to grain‐boundary diffusion and chemical impurities in the specimens used earlier.This publication has 4 references indexed in Scilit:
