Abstract

The electroplastic effect is studied on mechanically loaded single crystals of nickel-based CMSX-4 superalloy and pure aluminum bicrystals. Both objects of study exhibit elevated plasticity under electrical pulses. Traces of the electroplastic deformation that occurs in CMSX-4 single crystals at current densities J higher than 3 kA mm⁻² and aluminum bicrystals at J exceeding 1.6 kA mm⁻² are analyzed using a scanning electron microscope.
