“…where [V] is the amount (in mass%) of vanadium dissolved in austenite in equilibrium at the given temperature and [N] is the N content (in mass%) in steel; [V] × [N] is the vanadium and nitrogen solubility (in mass%) in austenite; and T is the temperature. At an austenization temperature of 1150 • C (1423 K), the equilibrium-dissolved vanadium quantity can be calculated by Equation (2), which is found to be 0.16% (N content of 0.02 mass%). The contained vanadium was completely dissolved into austenite in Steel D. At a cooling rate of 20 • C/s, the starting transformation temperatures, Ar 1 , of Steel A, Steel B, and Steel D were found to be 610, 600, and 598 • C, respectively.…”

“…High carbon steels with a fully pearlitic microstructure are widely applied in rail steels, spring steels, wire ropes, tire reinforcement, and high-strength bars because of their high strength, excellent wear resistance, and fatigue failure resistance [1][2][3][4]. However, the applications of high carbon steels are limited in precision instruments, tools, and small parts because of their susceptibility to brittle behavior.…”

In order to investigate the influence of vanadium microalloying on deformation-induced pearlite transformation (DIPT) of eutectoid steel, thermomechanical simulation tests were carried out in this study. The following four compositions of vanadium microalloying were applied in the tests: vanadium free in Steel A, vanadium content of 0.1 mass% in Steel B, vanadium content of 0.27 mass% in Steel C, and vanadium content of 0.1 mass% with the addition of 0.02 mass% N in Steel D. The dissolution of vanadium and precipitation of vanadium carbides, nitrides, or carbonitridesand the effect of vanadium microalloying on the fraction and morphology of deformation-induced pearlite for different magnitudes of strain were examined, and the mechanism of the effect was elucidated. The results revealed that DIPT could be significantly improved by vanadium microalloying with the addition of N but decreased and postponed without the addition of N because vanadium nitrides or carbonitrides were precipitated in austenite under a small strain and facilitated the nucleation of pearlite both along the boundary of austenite grain (AG pearlite) and intragranular (IG pearlite). Moreover, transformation kinetics of DIPT was fitted and compared. The results further revealed that the rate of DIPT in vanadium-microalloyed steel with the addition of N was twice as fast as that in the vanadium-free steel. In order to ensure the complete spheroidization of lamellar cementites in vanadium-microalloyed steel, a comparison of the morphology of cementites revealed that a greater magnitude of strain was required.
