✦ Synopsis

Using scanning electron microscopy SEM and transmission electron microscopy TEM , the mi-( ) crostructure of a new super-high-strength Al᎐Zn ᎐Mg᎐Cu alloy C912 has been investigated. Compared with some other high-strength aluminum alloys, the C912 alloy exhibits higher strength and good stress-corrosion resistance and its specific strength is even higher than some Al᎐Li alloys. Its potential for use in the Chinese AE100 airplane is discussed.
