摘要
通过实际的热轧实验,研究了轧后冷却速度对C-Si-Mn系热轧双相钢组织形貌和力学性能的影响。研究发现,轧后冷却速度对热轧双相钢的显微组织和力学性能有很大的影响。热轧双相钢具有三种典型的组织形貌,而不同的组织形貌通过不同的强化机制赋予热轧双相钢不同的力学性能。通过不同冷却速度下的双相钢热轧实验,可以使热轧双相钢获得良好的力学性能。
The effects of cooling rate on microstructure and mechanical properties of C-Si-Mn dual-phase steel as-hot-rolled were studied by hot-rolling experiment. It is found that cooling rate has an great effect on the microstructure and mechanical properties of as-hot rolled dual-phase steel. There are three typical microstructure of as-hot rolled dual-phase steel and through different strengthening mechanism to obtain high yield strength and tensile strength. The yield strength and tensile strength can be obtained by controlling the cooling rate,and the result is better.
