Abstract：Because 5000 series aluminum alloy has good tensile mechanical properties and formability,it is used as automobile lining plate and complex structural parts.Compared with other traditional modifiers,Ce-rich rare earth(RE)can not only refine the grain of aluminum alloy,but also improve the morphology,size and distribution of the second phase in the alloy structure.The characteristics and research progress of 5000 series aluminum alloy were reviewed,the role of rare earth in aluminum alloy was summarized,and the strengthening mechanism of Ce-rich rare earth on 5000 series aluminum alloy was analyzed emphatically.
