| Abstract: | According to the thermal-mechanical theory and the solubility formulae of VN and VC in austenite, the theoretical calculating methods for the solubility of V, C and N in austenite and the compositional coefficient of V(C,N) were proposed. The calculations for the typical V-bearing steels were carried out, and the calculating results were discussed. |

| Keywords: | V-bearing microalloyed steel V(C N) equilibrium solubility compositional coefficient austenite |
