| 摘 要： | 采用Gleeble-1500热模拟试验机,对硼钢板B1500HS进行单向等温拉伸物理模拟实验,研究其热冲压流变行为.分析温度及应变速率对材料流动特性的影响,比较Hansel-Spittel和Noron-Hoff两种流变模型与实验数据的拟合精度.依据Hansel-Spittel流变模型的缺陷,提出一种修正的Hansel-Spittel流变模型(S-Hansel-Spittel),为准确描述硼钢板B1500HS在奥氏体状态的流动特性提供帮助. |
| 关 键 词： | 超高强硼钢板 流变模型 奥氏体 |

| Abstract: | Tensile experiments at constant high temperature were carried out for hot stamping of boron steels B1500HS on the test machine Gleeble-1500 to get stress-strain curves.The deformation behavior of hot stamping of boron steels B1500HS was investigated.The influence of deformation temperature and strain rate on flow characteristic was analyzed.The difference among Hansel-Spittel rheology law,Noron-Hoff rheology law and experimental data was compared and investigated.In order to overcome the shortcomings of Hansel-Spittel rheology law,the simplified Hansel-Spittel rheology law was proposed,which can help precisely describe the flow characteristic of boron steels B1500HS in austenitic state. |
| Keywords: | ultra-high strength boron steels rheology law austenitic |
