摘要：

The effect of additions of vanadium with simultaneous additions of other carbonitride forming microalloying elements ( Ti, Nb, Zr) or Al on the hardenability of steels of composition Fe-0.4C-1.5Mn-(-0.004-0.021)N (wt-%) was investigated. Using a thermodynamic model, the composition of the austenite and the amount of undissolved carbonitride formed by microalloying elements for each austenitising temperature were determined. The relationships between the hardenability parameters and the calculated austenite composition as,well as the amount of undissolved carbonitride were studied. The optimum conditions for increasing the efficacy of vanadium as a hardenability agent were established. MST/3956.
