摘要：
Nuclear fusion energy has been reckoned as a key solution to addressing global energy and environmental challenges. However, pure tungsten (PW), as the most promising plasma-facing materials (PFMs) is unsuitable for application in the future fusion reactors with more demanding environment due to its low recrystallization temperature (RCT), high ductile-to-brittle transition temperature (DBTT), and high irradiation-induced embrittlement susceptibility. This paper reviews the damage mechanisms of PW and the trending W-based candidate PFMs under helium ion (He+) irradiation, focusing on He bubble formation and irradiation-induced micro- structural evolution. It also provides a comprehensive assessment of recent advances and challenges in improving the irradiation resistance of W-based materials. This review aims to guide future research on W-based materials under He+ irradiation conditions.
