Abstract
The dependence of the transformation kinetics of an HSLA steel and related C-Mn steels on the austenitisation conditions have been investigated using calorimetry and dilatometry. It is observed that the ferrite-start temperat ure depends both on the manganese content and on the amount of niobium in s olution. Calculations of the transformation kinetics based on an interface- mobility model applied in a tetrakaidecahedron austenite-grain geometry are used to investigate the background of the observed changes in transformati on kinetics.
