Abstract
ABSTRACT Comparative experiments on different decarburisation processes of Fe-C alloys in Ar-CO-CO2 and Ar-H2O-H2 atmospheres were carried out. The fundamental principles of carbon distribution, migration, and conversion are elucidated during decarburisation in both atmospheres. The completely decarburised layer of 2-mm-thick strip in Ar-CO-CO2 atmosphere appeared about 20 min later than the decarburisation in Ar-H2O-H2 atmosphere. Compared with the decarburisation in the Ar-H2O-H2 atmosphere, the carbon-rich phase dissolution zone is wider and the solid solution carbon content in the centre side is lower in the Ar-CO-CO2 atmosphere. The concentration gradient of solid solution carbon on the centre side of the interface of austenite zone in Ar-CO-CO2 atmosphere is smaller than that in the Ar-H2O-H2 atmosphere.
