Abstract
The change of specific volume due to isothermal decomposition of Fe-C auste nite into ferrite and carbon enriched austenite above the A(1) temperature, and subsequently into ferrite and cementite below the A(1) temperature, ha s been calculated quantitatively, using recent lattice parameter data for t he phases involved. Corresponding dilatometric experiments have been perfor med for various Fe-C alloys. It follows that the measured relative length c hanges by isothermal decomposition of austenite above and below the A(1) te mperature are in good agreement with the calculated results.
