N2 - The aim of the present work is to study the microstructure evolution of a
cold‐rolled low carbon steel alloyed with Cr, Mn, Mo, and Nb during
continuous heating. The formation of austenite and its further
transformation is examined by means of peak annealing experiments at
three different heating rates, followed by quenching. The effect of
carbide‐forming alloying elements in the kinetics of austenite formation
and decomposition is discussed with the aim of DICTRA calculations.
Electron Probe Micro Analysis allows the detection of small
compositional fluctuations within the microstructure, which are
responsible for local changes in the mechanism of austenite formation.
It is experimentally demonstrated that the temperature dependence of the
austenite fraction is relatively insensitive to the heating rate. It is
suggested that carbide‐forming alloying elements slow down the kinetics
of austenite formation.
