CSP工艺热轧400MPa汽车板组织与力学性能的研究
RESEARCH ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF HOT ROLLED 400?MPa STEEL BY CSP PROCESS
【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。
【Abstract】 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.
