摘　　要：研究了用CSP工艺热轧生产的 4 0 0MPa汽车板的组织和力学性能。通过拉伸和弯曲试验以及金相观察 ,认为晶粒细小是CSP工艺能够生产高强度、高塑性汽车板的主要原因。This paper sutdies the microstructure and mechanical properties of 400?MPa hot-rolled automobile sheet produced by CSP process. According to results of tension and bend tests and microstructure observations, the fine grain can be considered the main reason for the hot-rolled sheet to have high strength and excellent elongation.

关 键 词：CSP 低碳钢 高强度 组织 性能
