全面评述了7xxx系铝合金氢脆(HE)问题的国内外研究现状,讨论了氢脆机理以及氢脆的影响因素,并介绍了几种重要的测试方法.针对目前研究工作中尚未从理论上揭示氢脆本质这一突出问题,指出了今后7xxx系铝合金氢脆问题的研究方向,同时结合前期的研究工作,提出了具体的相关建议.
The domestic and overseas status of the investigations on hydrogen embrittlement(HE) in 7xxx series aluminum alloys is reviewed in detail.The HE mechanism and the influence factors are discussed,and then several test methods for HE are introduced.Based on the problem that the nature of HE has not been clarified theoretically so far,the future research on HE in high strength aluminum alloy is pointed out.Meanwhile,some relevant specific suggestions are put forward combined with the author's previous research work.
