摘要
采用高分辨透射电子显微镜观察纳米贝氏体钢中铁素体的结构,并通过内耗方法测定了纳米贝氏体钢中铁素体的位错密度.结果表明,纳米贝氏体钢铁素体中分布着高密度的位错,其平均位错密度约为6.4×1015m-2.
The high dislocation density in nanostructured bainitic steels was verified by high resolution transmission electron microscopy（TEM）.The dislocation density was measured by internal friction.The result shows that average dislocation density in nanostructured bainite is about 6.4×10^15 m^-2 using internal friction with medium frequency.
