| 摘 要： | 通过Thermecmastor-Z热模拟实验机对Ti-IF(无间隙原子)钢(%:0.009C、0.017Si、0.13Mn、0.012P、0.013S、0.05Ti、0.025Als)在750℃、850℃和变形速率0.1,1,20s-1下进行单道次压缩变形实验。得出Ti-IF钢加工硬化率-应变曲线、动态再结晶状态图和动态再结晶体积分数方程。实验结果表明,对于无明显峰值应变的应力-应变曲线,采用加工硬化率方法确定峰值应变和稳态应变是一种有效的方法。

| Abstract: | Single pass reduction deformation experiment of a Ti-IF （interstitial atom free） steel - 0. 009C, 0. 017Si, 0. 13Mn, 0. 012P, 0. 013S, 0. 05Ti, 0. 025Als with deformation rate 0. 1, 1 and 20 s-1 at 750 °C and 850 °C has been carried out by Thermecmastor-Z thermal simulation machine. The curves of work hardening rate - strain for the Ti-IF steel, the dynamic recrystallization diagram and the volume fraction equation of dynamic recrystallization were obtained. Test results show that for the stress-strain curves with no obvious peak strain, it is a available to use work hardening rate method to determine peak strain and stable strain. |
