Abstract In this work, the hot deformation behavior of 30Cr4MoNiV ultra-high-strength (UHS) steel is investigated by isothermal compression tests using the Gleeble-3500 thermal simulation machine at 1 173—1 373 K under the strain rate of 0.01—10 s^-1, and the optimized constitutive equation with strain-dependent constants suitable for 30Cr4MoNiV UHS steel is established. The results show that the flow stress increases with the increase of the strain rate and the decrease of the deformation temperature. The constitutive equation constructed by hyperbolic sine function has the highest accuracy among the three constitutive equations constructed by power law function, exponential function and hyperbolic sine function. Based on the hyperbolic sine function and the strain-dependent constants, the optimized constitutive equation can accurately predict the flow stress of 30Cr4MoNiV UHS steel in the process of hot processing.

Key words： ultra-high-strength steel hot deformation behavior constitutive equation strain-dependent constant
