AbstractNanostructures can form in several conventional materials under high current density electropulsing, for example, nanophases of alpha-Cu(Zn) and beta'-(CuZn) in a cold-worked alpha-Cu(Zn) alloy, nanosized gamma-Fe in a low-carbon steel, orientated nanosized TiC in a TiC/Ni(Cr) cermet and nanosized alpha-Al in an LC6 superduralumin. The mechanisms responsible for the above nanostructured transitions can be attributed to the competition of many factors induced by electropulsing, including high-rate heating, thermal stress, reduced thermodynamics barrier and large electron impacting. On the other hand, many low-energy dislocation configurations, large amounts of twins and stacking faults form in the brass and cermet under the electropulsing. The evolution of the above defects is closely associated with the electrical energy, thermal energy and the stress introduced by the electropulsing.
