On the variations in the mechanical characteristics of metals under the action of an electric potential

The effect of an electric potential φ ≤ 5 V on the creep and microhardness of a number of metals and alloys is considered. The creep rate and microhardness are shown to vary as an excess electric charge is induced on a surface by applying a potential from a voltage source or due to a contact potential difference. These effects are nonmonotonic and irreversible, and their nature is discussed.
