| Abstract: | Adding a small amount of rare earths to the alloys can play significant effect on the microstructures and mechanical properties. The research status of rare earths in aluminum alloys at home and abroad was reviewed. The influencing mechanism of rare earths was discussed. The effect of rare earths on grain size and yield strength of aluminum alloys was analyzed. The application prospect of rare earths in aluminum alloys was prospected to provide references for popularizing the application of rare earths in aluminum alloys and the study of strengthening the comprehensive properties of aluminum alloys. |
