Keywords： microalloyed forged steel

The dynamic recrystallization behavior of microalloyed forged steel was investigated with a compression test in the temperature range of 1 223--1 473 K and a strain rate of 0. 01--5 s-1. Activation energy was calculated to be 305. 9 kJ/mol by regression analysis. Modeling equations were developed to represent the dynamic reerystalliza-tion volume fraction and grain size. Parameters of the modeling equations were determined as a function of the Zener-Hollomon parameter. The developed modeling equation will be combined with finite element modeling to prediet microstructural change during the hot forging processing.
