We have experimentally demonstrated continuity of hypoeutectoid and pearlite ferrites in aggregates in the microstructure of low-carbon, low-alloy ferrite–pearlite steel. Such ferrite aggregates of various origins have been repeatedly observed along with hypoeutectoid ferrite and pearlite grains. We propose that aggregates of hypoeutectoid and pearlite ferrites should be regarded as a characteristic microstructural feature and this should be taken into account in microstructural characterization.
