Abstract
The carbon partitioning during bainite transformation was studied using a diametrical dilatometer. The relationship of Ms temperature as a function of carbon content was determined for 4317 type steels. Austempering experiments were performed in which the Mstemperature was measured as a function of austempering holding time and temperature. The minimum values of carbon content in the residual austenite were determined from measured Ms temperature values and the relationship to carbon content. The results are compared to the T0 carbon composition calculated by ThermocalcTM for each austempering temperature assuming paraequilibrium. Good agreement is found between the calculated T0 composition and the final austenite composition.
