The development of dynamic analysis of migration in the materials

用透射电镜对铁或氧化铁与碳的反应进行了现场观察。利用铁表面的碳沉积和FIB制备TEM试样，实现了铁与碳的接触。该反应发生在600℃左右，铁析出并向碳层生长。在TEM中，钙也被移到了氧化铁的边缘，这表明了控制制渣的可能性。

The in-situ observation of the reaction between iron or iron-oxides and carbon in TEM was carried out. The contact between iron and carbon was realized utilizing the carbon deposition on the surface of iron and FIB enabled to prepare TEM specimens. The reaction occurred around 600℃ as the precipitation of iron and growth into carbon layer. Calcium was also moved to the edge of iron oxides and it indicated that the possibility of the controlling making slag in TEM.
