摘要

本发明涉及一种锰配分和逆转变800MPa低碳Q&P钢制备方法，该方法先将材料以将材料以一次锰配分：以一定速率加热到双相区某一温度并保温，随后将材料以一定速率加热到奥氏体单相区某一温度并保温后将材料水淬至室温；然后进行逆转变处理，即将材料以一定速率加热到双相区某一温度并保温，之后将材料快速转移到M_S与M_f之间某一温度进行淬火保温一段时间，最终将材料水淬至室温。本发明采用锰配分与综合配分、逆转变工艺有机结合，碳、锰元素得到高效利用，残余奥氏体的稳定性获得大幅度增强，低碳‑锰‑硅钢的综合力学性能得到极大的改善。在同等汽车安全性能要求下可以极大地减轻车身的重量，降低生产成本及能源消耗。

3. IMPROVED METHOD FOR PRODUCING A COLD REDUCED LOW CARBON STEEL BELT AND LAMINAR MATERIAL. "," The present invention relates to an improved method for producing a low carbon steel strip and sheet material, cold reduced; Said method comprises the steps that consist of: providing a piece of low carbon steel, totally deoxidized and vacuum degassed; hot rolling until an intermediate thickness is obtained; remove the scab by hot rolling; reduce in cold until the final thickness is achieved and recognize; This method is characterized in that the steel essentially contains,in percentage by weight: from 0.02 to 0.10 of carbon; 0.1 to 0.9 manganese; 0.02 to 0.18 for columbium, residual phosphorous, sulfur, silicon, oxygen, and nitrogen; 0.01 to 0.08 aluminum, the rest consisting essentially of iron, except for incidental impurities; the columbium is completely materially combined; the hot rolled material is cooled to a temperature not higher than 705ºc .;the hot-rolled material is cold-reduced to [P] .
