By measuring the dilatometric curves of 15MnVB steel with cooling speed 0.05 ~20 ℃/s on Gleeble-1500 thermo-mechanical simulator
and combining with metallographic analysis
a CCT diagram of hot deformed austenite in continuous cooling transformation was obtained
and the products microstructure and hardness of the continuous cooling transformation occurring in steel 15MnVB was investigated. The results show that the microstructure of the steel consists of ferrite + pearlite
ferrite + pearlite + bainite
ferrite + pearlite + bainite + martensite and bainite + martensite at the cooling rate from 0.05℃/s to 20 ℃/s.
