摘　　要：采用Gleeble-3800热模拟试验机对20CrMnMo钢的连续冷却转变动态CCT曲线进行模拟,研究了不同冷却速率对组织性能的影响,结果表明:当冷却速率小于1℃/s时,奥氏体转变产物为铁素体和珠光体,冷却速率大于3℃/s时产生马氏体组织,很好地指导了轧制工艺的制定,有利于改善盘条的加工性能。To simulate CCT curve of 20 CrMnMo steel using Gleeble-3800 thermal simulator.The effect of cooling rate on microstructure and properties was studied.Results showed that austenite transformation products was ferrite and pearlite when cooling rate was lower than 1.0℃/s,austenite transformation products was martensite when cooling rate was higher than 3.0℃/s,which can guide the establishment of rolling process and improve the processing property of wire rod.
