The properties and microstructural changes of cerium-containing high-strength Al-Li alloy under external electric field were investigated. The electronic mechanism of electric field was discussed. The electric field increases the ductility of the alloy, while the strength of the alloy is essentially unchanged, changing the fracture characteristics of the alloy and promoting the dispersion of the precipitated phase of the alloy. Changes in the electron density of the alloy structure and performance changes.
