铝合金应力腐蚀开裂的影响机制
|
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.
