英文摘要	The microstructures of the Chinese RAFM steel irradiated at 773 K with 792 MeV Ar-ions to fluences of 2.3 x 10(20) and 4.6 x 10(20) ions/m(2), respectively, were investigated by using a transmission electron microscope with the cross-sectional specimen technique. Preferential nucleation and enhanced growth of the cavities at the interface between the second-phase particles and the matrix were observed in the irradiated specimen. The observation of the cavity-particle complex at lower dose indicated that the dose threshold for a cavity formation at the interface between MC particle and matrix was lower than that in matrix. With increasing irradiation dose, it was found that the second-phase particles changing their shape by attached cavities occurred. Furthermore, the role of the particle-matrix interface on nucleation and growth of the attached cavity with an increase of the dose were discussed in this work. (C) 2013 Elsevier B.V.
