研究了一种新型弥散沉淀强化NiMo合金的抗He离子辐照强化机理。显微结构观察表明，Mo2C微粒与Ni基体之间以及SiC纳米颗粒与Ni基体之间的界面可以有效地捕获He气泡，从而协同抑制Ni基体中He气泡的形成和长大。结果表明，适量的Mo2C微粒和SiC纳米微粒能有效地提高抗辐照硬化性能，有利于抗辐照镍基合金的优化设计。
The mechanism for outstanding resistance to He-ion irradiation-induced hardening of a novel dispersion-precipitation strengthened NiMo alloy has been investigated. Microstructural observations show the interface between Mo2C micro-particles and Ni matrix and between SiC nanoparticles and Ni matrix can effectively trap He bubbles, thus synergistically inhibiting the formation and growth of the dissociated He bubbles in the Ni matrix. It suggests that the reasonable high amounts of well-dispersed Mo2C micro-particles and SiC nanoparticles can effectively improve the inhibition efficiency of irradiation-induced hardening and are beneficial for the optimization and design of irradiation-resistant Ni-based alloys.
