Deformation greatly promoted carbonitride isothermal precipitation and made C-curve shift leftwards. The position and shape of C-curve depended on the content of Nb and N to a great extent, C-curve shifted leftwards a little when N content increased and its nose temperature was raised with Nb content increased. 3 when cooling rate increased, start temperature and finish temperature of continuous cooling precipitation decreased, full precipitation became difficult to take place, the volume fraction of carbonitride precipitation decreased, molar fraction of Nb and C dissolved in austenite increased, and the precipitation grain was further refined. Deformation shorten precipitation start time during continuous cooling, raised precipitation start temperature, accelerated precipitation kinetics of carbonitrides.
