摘要	Abstract 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.
