Research on Simulating of Controlled Rolling and Controlled Cooling Process for Mo Micro-alloy Steel

摘要：

The transformation production and recrystallization for Mo Micro-alloy Steel had been carried out on the Gleeble-3800 thermo-mechanical simulator. Based on the schedule, TMCP was applied to two stages multi-pass hot rolling experiments and the influences of the technological parameters on microstructure and mechanical property were analyzed.The results showed that the microstructure, precipitation and mechanical property of Mo Micro-alloy steel were strongly affected by the start-rolling temperature, the end-rolling temperature, the cooling rate and the relaxation time. The appropriate parameters were used and the ideal volume fraction of the acicular ferrite was observed by using metallographic microscope and transmission electron microscope(TEM).
