Abstract
Measurements have been made of the rate of absorption of carbon from CO-CO2 mixtures into stagnant liquid iron and of the rate of unidirectional dissolution of graphite into stag-nant liquid iron and iron-carbon alloys at 1560°C. Total absorptions and concentration pro-files were found to be consistent with a composition dependent chemical diffusivity given byD = 1.1 (1 + wt pct CJ5.3) X 10∼4 cm2Js with an uncertainty of about ±0.2 x 10-4. It is shown that many of the previous determina-tions of the chemical and self-diffusivity are consistent with this suggested dependence.
