Abstract

Abstract: A single pass compression test was carried out on 10B21 cold heading steel by using Gleeble-1500 thermal simulator. The effects of deformation temperature (950, 1000 ℃), deformation rate (0.1, 1, 10 s^-1), pre-strain (0.10, 0.15, 0.20), prior grain size and interval time on the static recrystallization behavior of the 10B21 cold heading steel were studied. The austenite grains under different deformation conditions were observed, and the kinetic model of static recrystallization and the grain size model of the 10B21 cold heading steel were established. The results show that the volume fraction of static recrystallization is positively correlated with the deformation temperature, deformation rate, pre-strain and interval time. The static recrystallization grain size is positively correlated with deformation temperature, prior grain size, and negatively correlated with deformation rate and pre-strain. The static recrystallization activation energy of the 10B21 cold heading steel is 221 036 J/mol. The correlation coefficient R²=0.99 between the experimental value and the calculated value of the grain size model indicates that the accuracy of the predicted value of the model is high.
