Abstract:
The growth of grain boundary carbides (GBC) has been followed after heating to 920 °C/min to room temperature in plain carbon steels at two Mn levels. In ferrite/pearlite steels, the GBC form the tails to the pearlite colonies. The thickness of GBC is related to the pearlite reaction, since the temperature at which this occurs controls (a) the thickness of carbide nuclei and (b) the amount of carbon available for precipitating out onto these tails. Increasing cooling rate and Mn level decreases the transformation temperature, and leads to finer carbides. The pearlite nose transformation temperature should be
