| Abstract: | 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 6.4×1015 m-2 using internal friction with medium frequency. |
