The paper describes the features, scientific and practical prospects for the use in the foundry of the conductive electric current treatment of melt by several types of current simultaneously.

The detailed microstructure and texture evolution was studied using electron backscatter and X-ray diffraction analysis. For comparison, conventional heat treatment at 400, 500 and 600 °C were also applied to the cold-rolled sheets.

Inorganic n-type Bi2Te3 flexible thin film, as a promising near-room temperature thermoelectric material, has attracted extensive research interest and application potentials. In this work, to further improve the thermoelectric performance of flexible Bi2Te3 thin films, a post-electric current treatment is employed. It is found that increasing the electric current leads to increased carrier concentration and electric conductivity from 1874 S cm−1 to 2240 S cm−1. Consequently, a high power factor of ~10.70 μW cm−1 K−2 at room temperature can be achieved in the Bi2Te3 flexible thin films treated

Abstract:

Owing to its unique properties, silver (Ag) in the form of nanoparticle (NP) ink promises to play a vital role in the development of printed and flexible electronics. Once printed, metal NP inks require a thermal treatment process called sintering to render them conductive. Among the various methods, electrical sintering is a highly selective and rapid sintering method. Here, we studied the electrical sintering of inkjet-printed Ag NP lines via a stepwise current increment sintering (SCIS) technique. In the SCIS technique, the supplied electric current was gradually increased in multiple steps

Abstract:

A rapid aging treatment method of Al-7Si-0.55Mg alloy using electric pulse, namely electric pulse aging treatment, is explored in this study. The effect of electric pulse assisted aging on microstructure and properties of Al-7Si-0.55Mg alloy are investigated by means of optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), tensile tests and hardness tests. The results show that the microstructure of the Al-7Si-0.55Mg alloy is effectively refined, and the morphology of eutectic Si changes from long and thin strip to a spherical shape or short rod.

Abstract:

Electrochemical treatment of oil industry wastes such as oil sludge with a high content of mechanical impurities or oil-contaminated soil is one of the effective methods of cleaning the environment directly at the site of contamination. A feature of the technology is the possibility of generating toxic gas emissions. This article analyzes this aspect of the electrochemical cleaning method implementation. Laboratory experiments on the treatment of waste samples containing oil and formation water with electric current were carried out, and gaseous compounds formed during the experiments at diffe

Abstract:

With spintronics applications in mind, we use irreversible thermodynamics to derive the rates of entropy production and heating near an interface when heat current, electric current, and spin current cross it. Associated with these currents are apparent discontinuities in temperature (ΔT), electrochemical potential (Δ[Formula: see text]), and spin-dependent “magnetoelectrochemical potential” (Δ[Formula: see text]). This work applies to magnetic semiconductors and insulators as well as metals, because of the inclusion of the chemical potential, μ, which is usually neglected in works on interfac

Abstract:

Electropulsing treatment was applied to high carbon pearlitic steel to assess the effects of the treatment on microstructure and properties. Ferrite recrystallisation and cementite spheroidisation were induced in samples treated at pulse duration and frequency greater than 40μs and 50Hz, respectively. Ferrite grain size of electropulsed samples was refined compared to similarly annealed samples. The results are explained through a combination of heating and athermal dislocation and atomic mobility effects. With optimisation, electropulsing may offer an improved annealing processing method.

Abstract:

In this work, the electric–thermal effect of a carbon-fibre-reinforced epoxy composite (CFRE) panel was studied, as well as the influence of the electric heating treatment on the mechanical properties of the composite. It was observed that the temperature of the composite increased rapidly once the current was loaded, and the equilibrium surface temperature was reached within 2 min. The electric–thermal effect and mechanical properties depended on both the current loading time and the current intensity. At 5A, the flexural modulus and strength of the CFRE increased before decreasing with the c

Electrochemical treatment of contaminated soils is an actual method for the remediation of industrial and urban areas. It represents a good alternative to methods of mechanical, thermal, chemical and biological treatment, and, if necessary, can be used with them. Passing electric current through the soil allows to reduce the concentration of such pollutants as oil and oil products at a considerable depth, to successfully reduce the content of dissolved mineral salts. In recent years a number of works of scientists around the world have been devoted to the study of such technologies. This artic

The sewage sludge formed at wastewater treatment plants constitutes a small percentage of the volume of treated wastewater. However, the costs associated with sludge treatment and disposal account for the lion's share of the operational expenses of wastewater treatment plants. The sludge contains harmful and toxic substances. On the other hand, sludge is a source of carbon, nutrients, and trace elements, meaning it can be effectively utilized. An important stage in sludge disposal is its dewatering, particularly with the use of electric current. The study investigated the electro-dewatering of

ABSTRACTThe present paper investigates the use of electric current treatment in improving the drawability of plain carbon steel wire for high strength steel applications. The mechanical properties for wires of composition 0.80C 0.65Mn 0.27Si wt.% of diameters 4.09 and 3.00 mm dry drawn from 10.00 mm rods are characterised. The total number of passes for 4.09 and 3.00 mm diameter wires are 7 and 10 respectively resulting in true strains of 1.79 and 2.41.
