Abstract:
     The effect of cooling rate(1~30 ℃/s) and coiling temperature(650~550 ℃) on the fine precipitates in ferrite was studied on Gleeble thermomechanical simulator with a commercial Nb V Ti microalloyed complex strip steel.The results shown that an interphase precipitation of 10~20 nm was observed under condition of 1~5 ℃/s cooling rate.
