An Assessment of the Si Mobility and the Application to Phase Transformations in Silicon Steels
-
Peter Franke
Abstract
The mobilities for diffusion in Fe – Si alloys with bcc and fcc structure have been assessed using the DICTRA software: In the bcc phase the mobilities of both elements are determined as functions of temperature and composition. In the fcc phase the mobility of Si is evaluated as a function of temperature. Using these parameters and the data for carbon diffusion from a database, the kinetics of ferrite growth from Si-containing austenite is calculated and compared with experimental results.
Abstract
Die Beweglichkeiten für Diffusion in Fe–Si-Legierungen mit bcc und fcc Struktur sind mit dem DICTRA Programm ausgewertet worden. In der bcc-Phase werden die Beweglichkeiten beider Elemente als Funktion von Temperatur und Zusammensetzung ermittelt. In der fcc-Phase wird die Beweglichkeit von Si als Funktion der Temperatur ausgewertet. Unter Verwendung dieser Parameter und der Daten für Kohlenstoffdiffusion aus einer Datenbank, wird die Kinetik des Ferritwachstums in Si-haltigem Austenit berechnet und mit experimentellen Ergebnissen verglichen.
