THE NEGATIVE ELECTROPLASTICITY IN THE Zn-5Al ALLOY
|
Abstract:
The Zn-5Al eutectic alloy is superplastically deformed in an electric field of 0.3MV.m-1,and displays the negative electroplasticity The effect of electric field on the strain rate is relative to the effect of the surface charges on the voids on the sudece. The electric field produces inductive charges on the sudece of the specimen, which produce5 voids in the sudece and decreases the strain rate of the alloy in deformation.
