Abstract

Rare earth element is widely used in a variety of metal materials due to the effective and stable modification.The modification can refine alloy structure

thus improving mechanical properties

and the modification effect of different rare earth elements on aluminum alloy is different.The influence of several rare earth elements on the microstructure and mechanical properties of aluminum alloys as well as the modification mechanism was mainly introduced.Meanwhile

the present research status of rare earth aluminum alloys at home and abroad was reviewed.The existing problems were discussed and the future research was prospected.
