Recrystallization and grain growth in austenitic stainless steels: a statistical approach

摘要

A mathematical model, able to describe the recrystallization and grain growth in metals, has been developed. Takinginto account the classical constitutive equations of the Taylor’s theory, the model involves only two free parameters(the dislocation density and the initial number of nuclei). Results from the model are here discussed in comparison withmeasurements performed on an AISI 304 stainless steel. The predictions of the model are in good agreement withexperimental results. As cross check of the model prediction, the independent parameter “dislocation density” wasfound to properly correlate to the mechanical properties of the steel and to X-ray diffraction measurements, according toTaylor’s and Debye’s relations respectively.
