Abstract The issue, structural response of the amorphous-nanocrystalline alloys (ANA) under neutron irradiation, has been investigated by a series of simulations and calculations. It is found that the irradiation-induced vacancies are fully annihilated by the migration of the phase boundary between the nanocrystal and amorphous or liquid zones. In addition, there is an effective self-recovery in the amorphous zone and in particular the nanocrystal region, because the nanocrystal phase is more competitive than the amorphous phase during quenching. This work reveals a unique and effective structural self-healing mechanism in the ANA materials, and will shed light on the development of new materials with high irradiation resistance.

中子辐照下非晶-纳米晶合金的有效自愈行为

摘要 通过一系列模拟和计算研究了非晶纳米晶合金 (ANA) 在中子辐照下的结构响应问题。发现辐射引起的空位被纳米晶体和非晶区或液体区之间的相界的迁移完全消灭。此外，在非晶区，特别是纳米晶区存在有效的自恢复，因为在淬火过程中纳米晶相比非晶相更具竞争力。这项工作揭示了 ANA 材料中独特而有效的结构自修复机制，将为开发具有高抗辐照性的新材料提供启示。
