| 摘 要： | 采用高速锤加载方式，研究了一种高碳低合金钢处于非剪切变形加载条件下的热塑剪切带的形成发展规律，试验结果表明：在目前的加载速率下，形成的剪切带是一种变形带，而不是相变带，带的形成与材料内部的二相粒子的尺度大小没有太大的关联。

| 关 键 词： | 高应变率 热塑剪切带 粒子尺度 低合金钢 |

| Abstract: | By way of high rate hammer loading,the forming and developing law is studied of thethermoplastic shearing band of a kind of high-carbon low-alloy steel under non.shearing de-formation loading conditions. Experimental results show that,at the present loading rate,theshearing band formed turns out to be a deformed band,not a phase-changed one,and the for-mation of the band does not have much to do with the size of the second phase grains in thematerial. |

| Keywords: | high strain rate thermoplastic shearing band grain size |
