Effect of titanium on the allotriomorphic ferrite transformation kinetics in medium carbon–manganese steels

The influence of titanium on the transformation kinetics of allotriomorphic ferrite during the isothermal decomposition of austenite has been investigated by means of dilatometric and microstructural analysis in medium carbon–manganese steels. A careful comparison of the transformation kinetics curves of a C–Mn steel and a Ti microalloyed C–Mn steel shows that Ti enhances the allotriomorphic ferrite transformation.
