Electric field treatment(EFT)was applied on GH4169 alloy during aging at 500-800 ? C to investigate the microstructure and property variation of the alloy under the action of EFT.The results demonstrate that the shortdistance di?usion of Al,Ti,and Nb atoms can be accelerated by EFT,which results in the coarsening of γ and γ phases.Meanwhile,lattice distortion can be caused by the segregation of Fe and Cr atoms,owing to the vacancy flows migrating toward the charged surfaces of the alloy.Therefore,the alloy is hardened by the application of EFT,even if the strength of the alloy is partly reduced,which is caused by precipitation coarsening.
