摘要 实验Q&P钢(0.31C-1.32Si-1.35Mn)在Gleeble3500上模拟Q&P工艺,经900℃奥氏体化后淬火至290℃,保温15 s后升温至配分温度450℃,分别保温10、60和120 s后淬火至室温。为了解决在Gleeble3500上初始淬火过程中冷速不均的问题,本文采用分段淬火的方法。结果表明,采用改进淬火方法并且配分时间为60 s的实验钢,具有高的强塑积,并且组织中存在明显的板条马氏体及条间稳定的残余奥氏体。 The heat treatment process of the experimental Q＆P steel （wt%： 0.31 C, 1.32Si, 1.35Mn） plat was simulated by Gleeble3500 with austenizing at 900℃, quenching at 290 ℃ for 15 s, heating to partitioning temperature 450℃for 10, 60 and 120 s, then quick cooling to room-temperature. A two-step quenching method was involved into the initial quenching process of Q＆P by Gleeble3500 to solve the problem of uneven cooling rate. The results show that with improved quenching process and partitioning for 60 s, it is available to assure carbon atoms accumulating into retained austenite from martensite and get high strength-elongation.
