Kinetics of the Simultaneous Decomposition of Austenite into Several Transformation Products

S. J. Jones and H. K. D. H. Bhadeshia


Transformations in steels rarely occur in isolation. This paper describes a modification to the Avrami overall transformation kinetics theory as adapted by Cahn, for grain boundary nucleated phases. The modification deals with the simultaneous occurrence of two or more transformations. Th emethod is demonstrated to faithfully reproduce published data on the volume fractions of allotriomorphic, Widmanstatten ferrite and pearlite as a function of chemical composition, austenite grain size and heat treatment (isothermal or continuous cooling transformation).
