摘　　要：综述了铁镍基和镍基高温合金中氢的渗透和氢脆的决定性影响因素棗氢陷阱和表面氧化保 护膜对这类合金抗氢渗透和氢脆性能的影响,提出了针对欲用作深海潜器小型核动力装置细棒状U-ZrH1.6燃料元件包壳的800H合金和690合金的抗氢渗透和氢脆性能评价需重点研究的方向。This paper reviews the determining influences of hydrogen traps and surface oxidation protective films in Fe-Ni based and Ni based high temperature alloys on their anti-hydrogen permeation andanti-hydrogen embrittlement properties, and pointS out the key research directions related to theassessment of the anti-hydrogen permeation and anti-hydrogen embrittlement properties of 800H and 690 alloys which may be used as U -ZrH1.6 fuel cladding in compact nuclear power reactors.
