| 摘 要： | 研究了等温处理Si-Mn低合金TRIP钢的拉伸性能和缺口敏感性与应变率 (ε =10 - 4～ 10 - 6s- 1)的变化关系。结果表明光滑试样下 ,Si -Mn低合金TRIP钢的屈服强度和抗拉强度随应变率的降低略有增加 ,缺口试样下 ,抗拉强度明显增大 ,缺口敏感性随应变率的降低明显增大。

| Abstract: | In this paper,effect of strain rate on the tensile property and notch sensitivity of Si-Mn TRIP steel after austenite tempering was invested.The results show that the yield and tensile strength of Si-Mn TRIP steel are increased slightly and total elongation is increased obviously with reducing strain rate.But the coefficient of notch sensitivity is depressed evidently with the strain rate decreased. |

| Keywords: | TRIP steel tensile property notch sensitivity strain rate |
