Query: Kinetic Theory of the Overlapping Phase Transformations   Often a number of precipitation processes in steels and alloys occur
simultaneously (they have the same origin in time) albeit at different rates.
Consequently, isothermic transformations are accompanied, in this case, by the
occurrence of second processes of precipitation that influence the changes of
the macroscopic parameter chosen for the kinetic study while first processes
are occurring. In this context a set-up is presented that addresses the issue
of characterization of nucleation and growth mechanisms of the individual
processes. Soft and hard interferences of processes are considered. The present
approach is based on the Avrami model and allows computing the kinetic
parameters (n, k) of the different precipitation processes in isothermic phase
reactions.
