| 英文摘要 | The development of high-temperature irradiation-resistant nickel-based alloys has been receiving much attention due to their potential applications in molten salt reactors (MSRs). Pure nickel and SiC nanoparticles dispersed nickel-based alloys (Ni-SiCNP composites) have been characterized by transmission electron microscopy (TEM) to determine the helium diffusion behavior under 3 MeV helium ion irradiation at 600 degrees C with ion fluence up to 3 x 10(20) ions/m(2). The TEM results indicated that the presence of dispersed SiCNP in nickel can inhibit the growth of helium bubbles, thereby mitigate the helium embrittlement and swelling of nickel-based alloys. The theoretical calculation results using the density functional theory (DFT) showed that the helium atoms prefer to diffuse to the interface between SiCNP and nickel matrix, and thus avoid the grain boundary segregation and also the growth of helium bubbles. This study confirmed the feasibility of dispersing carbides in nickel-based alloys to improve the irradiation-resistant performance of materials. (C) 2015 Elsevier Ltd. All rights reserved. |
