Abstract: The transformation behavior of V-bearing steel P510L for chassis frame girder under continuous cooling was investigated by means of MMS-200 thermomechanical simulator, with the CCT curves given statically and dynamically by thermal dilation in combination with metallography. The influences of deformation condition and cooling rate on the microstructure of the steel were analyzed. The results showed that the transformation of ferrite and pearlite is stimulated but that of bainite is inhibited through the deformation of austenite in low-temperature region, and the ferrite amount decreases and bainite amount increases with increasing cooling rate.
