Notizen:
The alloying behavior of RE element of Er in Al-Cu-Mg-Ag alloys with addition of Er wereinvestigated in this paper. During solidification ,most of element Er segregated at grain boundaries inthe form of primary Al8Cu4Er phase and part of Er dissolved in the α-Al matrix. After rolling,Al8Cu4Er phase could be fragmentated into dispersed particle which leaded to an increase of thegrain boundary strengthening . TEM observation and tensile strength test showed that small additionof Er retarded the precipitation of Ω phase and prolonged the time corresponding to the peakaging,with a remarkable increase of ductility
