Abstract
The interdiffusion coefficient in molten Fe-C alloy has been determined by the capillary-reservoir method in the temperature range from 1350°C to 1550°C under the concentration conditions that the initial carbon content of capillary sample CO was between 1.7 and 3.3% and the carbon content of reservoir melt Cs was the graphite solubility in molten iron.
The results obtained are summarized by the following Arrhenius equation:
