摘要
针对国产8 mm厚5083-H116铝合金,研究了敏化时间对其组织和性能的影响。结果表明,随着敏化时间的延长,5083铝合金微观组织中越来越多的β相(Al_(3)Mg_(2))沿晶界析出,并且形成大量的网状结构;5083铝合金腐蚀电位降低,晶间腐蚀倾向性持续升高,强度降低,伸长率提高。
The effect of sensitization time on the microstructure and properties of domestic 8 mm-thick 5083-H116 aluminum alloy was studied.The results showed that with the increase of sensitization time,more and more beta phases precipitated on grain boundaries,forming a large number of network structures,the corrosion potential of the aluminum alloy decreased gradually,the intergranular corrosion tendency increasesd,the strength decreasesd,and the elongation increasesd.
