Convergent beam electron diffraction (CBED) in transmission electron microscopy (TEM) was applied to determine local carbon concentrations in low-carbon transformation-induced plasticity (TRIP) steels. High-order Laue-zone (HOLZ) lines were experimentally obtained for comparison with simulation results. A new procedure for calculating carbon content is thus proposed. Retained austenite (RA) is classified into three types by morphology; the relationship between the carbon content and the corresponding RA morphology is discussed based on CBED results. Furthermore, results of X-Ray diffractometry measurements are also used for comparison.
在透射电子显微镜（TEM）中应用会聚束电子衍射（CBED）来测定低碳相变诱发塑性（TRIP）钢中的局部碳浓度。通过实验获得高阶劳厄区（HOLZ）线，以便与模拟结果进行比较。由此提出了一种计算碳含量的新方法。残余奥氏体（RA）按形态分为三种类型；基于CBED结果讨论了碳含量与相应RA形态之间的关系。此外，还使用X射线衍射测量结果进行比较。
