Abstract B92SiQL steel is favored by prestressed galvanized steel wire for its high strength and torsional resistance, and the thermal processing para-meters have an important impact on its deformation behavior and properties. In this study, the thermal compression experiments of B92SiQL steel were conducted over the range of deformation temperatures from 1 173 to 1 373 K and strain rates from 0.1 to 20 s^-1. The strain-compensated Arrhenius constitutive model was established based on the Zener-Hollomon parameter and linear fitting. The results showed that the flow stress decreased with increasing deformation temperature or decreasing strain rate. The thermal deformation activation energy (Q) of B92SiQL steel is about 305.865 kJ/mol. The linear correlation coefficient (R) between the predicted values and experimental values of flow stress obtained from this model is about 0.994, and the average absolute relative error (AARE) is about 2.800%. At lower deformation temperatures, the elongated primary grains were still present in the microstructure. At the thermal deformation condition of 1 373 K—0.1 s^-1, nearly complete dynamic recrystallization (DRX) occurred and the grains produced significant coarsening. The grain size was significantly refined when the strain rate increased to 10 s^-1. The critical stress and strain for the occurrence of DRX were determined from the curve of work-hardening rate and flow stress, and the critical condition was obtained to be exponentially related to the Z parameter. The DRX kinetic model of B92SiQL steel was deve-loped based on the conventional Avrami equation, and the predicted results were compared with the experimental data, which indicated that the model had high prediction accuracy.
