Transformations in steels rarely occur in isolation. This paper describes a modification of 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. The method is demonstrated to faithfully reproduce published data on the volume fractions of allotriomorphic. Widmanstaetten ferrite and pearlite as a function of chemical composition, austenite grain size and heat treatment (isothermal or continuous cooling transformation).
