摘要
在实验室试制了600MPa级低成本C-Mn系冷轧双相钢,比较了热轧态普通组织和退火后双相组织与力学性能的关系,分析了双相组织的强化机理,讨论了热轧卷取温度对最终力学性能的影响,分析并且优化了连续退火工艺参数。采用X衍射和电子背散射EBSD观察了试制双相钢组织的宏观与微观取向。
600MPa grade dual phase steels were piloted based on lower cost C-Mn alloy system in laboratory.Microstructure and property were compared between the hot rolled as received and annealing strip,strengthening mechanism of microstructure with dual phases was also analyzed.The influence of coiling temperature on mechanical property was discussed,and annealing parameters were investigated and optimized.Textures were examined by using X-ray and Electron Back Scattered Diffraction.
