“…To calculate the adiabatic rise in temperature, the properties of materials are shown in Table 4. An adequate thermal effect resulting from the Joule heating effect of electroplastic treatment is necessary to increase the nucleation rate of recrystallization [15]. The exact mechanism of athermal effect is still not very clear; however there is possibility that it results from additional force of electrons exert on a dislocation called electron wind, the Joule heating effect and thermal stresses.…”

The aim of this study is to report the use of non-conventional material removal process technique. It was found that electropulses (EPs) assisted drilling process improves the material machinability based on the eletroplastic influence. The influence of EPs in drilling process is studied by combining different feed rates, drills diameters and current densities in 7075 aluminium and 1045 carbon steel. The results show that the electrically assisted drilling process improves material machinability, decreases the specific cutting energy up to 27% in aluminium and 17% in steel.

“…The drawing forces of austenitic stainless steel wires, 77-79 copper wire, 80 and cast-ion wire 81 decreased in the EA drawing process, while their surface qualities improved. Tang et al 79 claimed that the temperature increase did not significantly contribute to the changes in mechanical properties, resistivity, and surface quality of austenitic stainless steel in the EA drawing process. In particular, Stashenko et al 82 stated that the EA drawing process can reduce the production cycle and product cost due to the decreased drawing force and increased drawing velocity.…”

The mechanical properties of metals change temporarily or permanently under application of electric currents under deformation. This phenomenon is often referred to as electroplasticity. The electroplasticity of metals and their alloys has been investigated under various loading conditions including tensile, compressive, bending, and hardness tests. Electrically-assisted manufacturing (EAM) utilizes this electroplasticity in manufacturing processes. Due to its technical advantages such as enhanced formability and reduced springback, EAM is energy efficient with reduced process time. Recent developments in EAM include various bulk deformation and sheet metal forming processes. This paper summarizes previously reported electroplastic behaviors of various metals or metal alloys and recent EAM processes. In addition, contemporary EAM patents are briefly reviewed.

“…10,11) They only analyzed the surface characteristics and mechanical properties. However, the recrystallization of metal wire using electrical current method has still not been examined, and in particular, the strain hardening exponent of the electrical current 304 wire is worthy of further investigation.…”

Electrical current process has been used in the thin plate metals and the fine wires because of its higher efficiency (rapidly recrystallization) and the advantage of avoiding oxidation without inert gas. This study investigated the transformation of twin structure and mechanical properties of 304 stainless steel after electrical current test by direct current. The results show the microstructure of matrix transported from preferred structure to equiaxed grains and a few annealed twins with increasing the current density of joule from 32 J to 188 J. The hardness of matrix remained stable under 83 J because of the number of twins increased, and the tensile properties were similar to the wire using furnace heating. After electrical current test at 188 J, the strain hardening exponent of wires was 0.44, was suitable to be used for cold work procedure.
