Due to its good strength to weight ratio, 2024 aluminum alloy (AA) is widely used in aerospace industry.Whether heat treatment affecting the stress corrosion cracking (SCC) behavior of this alloy was investigated in this study.A self-design uni-axial loading device was used to conduct the SCC test in 0.1 M NaCl solution.The experimental results showed that the susceptibility to SCC of the as-received 2024 AA depended on solution pH and stress level.This T4 heat treated alloy was more susceptible to SCC than the as-received one.SEM fractography showed that intergranular mode of SCC (IGSCC) occurred in 2024 AA regardless of heat treatment.

自2008年以来，太阳电池背板从原来进口TPT结构一家独大，逐渐发展到FFC、KPK、TPE、KPE含氟背板和PPE、AAA、APA等其它非氟材料背板，产品供应由原来全部进口到今天逐步国产化。未来国产化步伐会继续加快，国产背板将不仅在国内得到大量使用，而且也会像光伏组件产品一样逐步走向国际化，出口到世界各地。
