摘要
评述了7xxx系铝合金晶界偏析问题的国内外研究现状,讨论了晶界结构以及晶界偏析的实验研究。针对目前研究工作中尚未从理论上揭示晶界Mg偏析本质的突出问题,指出了今后7xxx系铝合金晶界偏析问题的研究方向,同时结合前期的研究工作,提出了相关的建议。
The domestic and overseas status of grain boundary segregation in 7xxx series aluminum alloys were reviewed in detail.The grain boundary structure and the grain boundary segregation were discussed.Based on the problem that the nature of Mg segregation has not been clarified from the view of theory so far,the future research on grain boundary segregation in 7xxx series aluminum alloys was pointed out.Meanwhile,some relevant specific suggestions were put forward combined with the author＇s previous research work.
