Abstract

Abstract: In order to study the effect of microalloying element Nb on dynamic recrystallization behavior of the high carbon alloy steel, a single pass compression test was carried out by using Gleeble-3500 thermal simulation tester, and the flow stress curve of the high carbon alloy steel at the deformation temperature of 950-1150 ℃ and the strain rate of 0.01-5 s^-1 was measured. The dynamic recrystallization grain morphology of austenite was observed by means of Zeiss optical microscope, the corresponding activation energy of recrystallization was obtained through regression calculation, and the thermal deformation equation was established. The results show that the dynamic recrystallization is easier to occur at higher deformation temperature and lower strain rate. The grain size of dynamic recrystallization of the high carbon alloy steel containing Nb increases with the increase of deformation temperature. When the deformation temperature is 1050 ℃, a large number of dynamic recrystallization grains in the high carbon alloy steel containing Nb can be obtained. The addition of 0.040% niobium to the high carbon alloy steel delays the onset of dynamic recrystallization of the steel by about 2.23 s when the strain rate is 0.1 s^-1 and the deformation temperature is 1150 ℃, and increases the activation energy of dynamic recrystallization deformation by 52.26 kJ/mol.

Key words: high carbon steel containing Nb, flow stress curve, dynamic recrystallization, recrystallization activation energy, microstructure evolution, thermal deformation equation
