Dislocation Substructure Gradient Formation in Aluminum by Creep under Weak Potential

Transmission diffraction electron microscopy of thin foils was used to study the dislocation substructure gradient of aluminum destroyed during creep. Creep under +1 V potential resulted in the formation of a dislocation substructure gradient, which was observed as a regular change in quantitative structural characteristics upon moving away from the sample fracture surface.
