利用原子探针层析（APT）、电子背散射衍射（EBSD）和透射电镜（TEM）分析了中国低活化马氏体（CLAM）钢的基体/基体界面（即晶界）和析出相/基体界面特征，以及界面上的溶质偏聚行为。结果表明，Cr、Mn、C、Si和P在基体/基体界面上富集，而Fe、W和V的偏析不明显。纳米碳化物的主要成分为C、Ta和V，VC颗粒与TaC相结合形成（V，Ta）C相，其最大直径约为40 nm，呈球形冠状。结果表明，Cr、W、P和Si在富V侧更容易偏聚，降低界面结合强度，导致沿晶断裂。
Characteristics of matrix/matrix interface, i.e. grain boundary, and precipitate/matrix interface on China Low Activation Martensitic (CLAM) steel were analyzed by Atom Probe Tomography (APT), electron backscatter diffraction (EBSD) and transmission electron microscope (TEM), as well as the solute segregation behaviors on those interfaces. It is found that the Cr, Mn, C, Si and P were enriched on the matrix/matrix interface, while the segregation of Fe, W and V were not obvious. The compositions of nano-size carbide were mainly C, Ta and V, and VC particle formed associated with the TaC and they are inter-soluble to form the (V, Ta)C, which exhibited a ball coronary morphology with maximum diameter about 40 nm. The results showed that the Cr, W, P and Si were more easily to segregate at the V-rich side, which might weaken the adhesive strength of interface and consequently result in intergranular fracture.
