| Abstract: | The effects of an electric field on the mechanical properties and the microstructure of Al Li alloy containing Ce were investigated, and the electronic mechanism of the effect was discussed. The experiment results show that the ductility of the alloy is enhanced by the electric field. The fracture features are changed and the precipitates are dispersed under the effect of an electric field. The effects of the electric field on the alloy are due to the change of the alloy electron density, which caused by the electric field. |
| Keywords: | rare earths electric field mechanical property fracture feature precipitates electron density |
