Unfortunately, few studies refer to the influence of vanadium. In this paper, the effects of different amounts of vanadium on phase transformation in high carbon steels during continuous cooling has been investigated on Gleeble1500 thermo–mechanical simulator, and the mechanical properties relevant to these effects have been measured. The results show that by the way of adding vanadium to the high carbon steel, the pearlite transformation temperature is depressed, the CCT curves of this transformation are postponed so that the interlamellar spacing is reduced, leading to the increase of the pearlite hardness and strength in the high carbon steel. There are two reasons why vanadium can depress the average temperature of pearlite transformation: firstly, vanadium depresses the start temperature of this transformation, secondl, it lowers the velocity of pearlite nodule growing. It is alsfund that ferrite appears on the austenite grain boundaries of the high carbon steel, introducin 0.1% vanadium into the high carbon stecan somewhat retrain the ferrite formation, nevertheless by the way adding 0.2% or 0.3% vanadium, the ferrite formation on the austenite grain boundaries is apparently prooted. Evidently, the ferrite formation on austenite grain boundaries is beneficial to the improvement of ductility of high carbon steels as confirmed in this paper.
