The combined homogenization treatment shortens the homogenization time, reduces the loss ofLi content and increases the ductity of the alloy.展开更多
Homogenization treatment under an electric field increases the distributive homogeneity of the T1 precipitation and improves the yield strength of 2091 Al-Li alloy.
