Abstract
The chemical diffusion coefficients and the solubility limits of copper in iron were determined in the temperature range 690–1050 °C by electron probe microanalysis. Specimens were large‐grained polycrystals for the γ‐iron and single crystals for the α‐iron. The iron contained less than 11 wppm of impurities and had a resistivity ratio R293 °K/R4.2 °K up to 8700. The results for the diffusion coefficients are (in cm2/s) DγCu=0.19 exp(−65 100/RT) and DαCu=300 exp(−67 800/RT). An anomalous decrease of the diffusion below the Curie point was observed.Keywords
