| 摘 要： | 介绍了通过试验研究得出的控轧控冷工艺对含Ti高强度汽车板组织和性能的影响。研究得出,钢中主要是细小的板条贝氏体组织,贝氏体板条内存在高密度位错,其板条细化和位错强化使钢的强度提高,而Ti的碳化物沿位错线弥散析出,进一步加强了析出强化效果。

| Abstract: | The influence of controlled rolling and controlled cooling process on microstructure and properties of Ti-contained high strength steel sheets for automobiles was studied.The results show that the fine lath-shaped bainite structure and high density dislocation were obtained,and the strength of steel sheet was increased.Titanium carbide precipitated dispersively along the dislocation lines and precipitation-strengthening effect was further enhanced. |
