摘要
轻质高强高韧铝合金在高铁、船舶、建筑、桥梁、化工机械和宇航工业等领域的应用不断扩大,对于铝合金服役的要求也越来越苛刻,针对铝合金的应力腐蚀开裂行为(Stress corrosion cracking,简称:SCC)虽然已经研究了半个世纪,但是提出的腐蚀机制却有着不同的解释。综述了铝合金SCC机制,并对影响铝合金应力腐蚀开裂的多种因素进行了分析,在此基础上,介绍了几种SCC试验研究的常用方法,为铝合金SCC的进一步研究提供有效的途径。
As aluminum alloy with light weight, high strength and high toughness is used more widely in high-speed rail, ships, buildings, bridges, chemical machinery, aerospace industry and other fields, the requirements for aluminum service are stricter ever. Aluminum stress corrosion cracking or SCC has been researched for half a century, but the corrosion mechanism was interpreted differently. The mechanism is summarized, the influential factors analyzed and common experimental methods stated. These efforts help pave a way in further study of aluminum SCC theory.
