Using the Heisenberg principle, the spin exchange between the neighboring spin is discussed. Heisenberg’s model describes the Hamiltonian of the system in terms of spin density and excitons. Mathematically, magnetic parameters such as magnetizations and magnetic susceptibility are determined by Green’s function. Ferromagnetism is expected from sp-d exchange interactions (RKKY), point defects such as oxygen vacancies, and Zn interstitial and quantum confinement effects. The spin-spin interactions mediated by<br />carriers gives rise to ferromagnetic ordering when the mean distance between Mn-Mn ions is sufficiently less than electron wavelength. The result is compared with experimental values and tested for Mn concentrations greater than 4%. In addition, the stability conditions are stated in terms of giant magnetoresistance. A shift in magnetic phase particularly from ferromagnetic to paramagnetic behavior is noticed at higher Mn concentration. A model is established to explain a shift in magnetic phases in terms of secondary phase and bound magnetic polarons. A calculation of magnetic susceptibility is carried out to verify the existence of ferromagnetism at Curie temperature. The investigation of ferromagnetism and superparamagnetism in Zn0.96Mn0.04O nanoparticles proves its multiple functions as read heads, dynamic random access memory, and spin random access memory. The medical and electronic application of Zn0.4 Mn0.6O is reviewed because Mn-doped ZnO nanoparticles have emerged as promising materials for cathodoluminescent, transparent conductive layer, biosensors, treatment for many viral disease, cancer treatment, medical imaging, and space applications.</p>2023-03-18T09:15:54+00:00Copyright (c) 2023 International Journal of Metallurgy and Alloyshttps://materials.journalspub.info/index.php?journal=IJM&page=article&op=view&path%5B%5D=935Recycling Multilayer Materials: Discovering Mechanical Parameters for Engineering Applications2023-06-15T10:19:59+00:00Yash Vermayashv0809@gmail.com<p>Multilayer materials have been widely used in various applications such as packaging, electronics, and construction industries. However, the disposal of these materials is becoming a significant environmental concern due to their non-biodegradable nature. Therefore, the recycling of multilayer materials has become an essential aspect of sustainable waste management. The mechanical characteristics of materials recycled from multilayer products were examined in this study. The focus was on determining the impact of recycling on the mechanical properties of the materials. We collected samples of multilayer materials and separated them into individual layers. The layers were then cleaned, processed, and reassembled into new multilayer materials. Testing was done on the new multilayer materials to determine their tensile strength, impact resistance, and elasticity. The results of the study indicated that the mechanical properties of recycled multilayer materials were influenced by various factors, such as the number of layers, processing conditions, and composition of the original material. To prevent their burning, placement in landfills, or reuse of their constituent parts, multilayer food packaging can be recycled. The material is made by joining numerous sheets together using temperature and pressure that are not applied simultaneously. The sheets are joined by the fusion of polyethylene and take place without the need of any other adhesives. Temperature, pressure, time, and the quantity of sheets are chosen as the factors, and their effects on the mechanical characteristics are calculated.</p>2023-03-01T00:00:00+00:00Copyright (c) 2023 International Journal of Metallurgy and Alloyshttps://materials.journalspub.info/index.php?journal=IJM&page=article&op=view&path%5B%5D=934Modern Material Concept to Produce Low-Loss Non- Oriented Electric Alloys2023-06-15T10:19:59+00:00Faraz Ahmadfaraz8298@gmail.com<p>The production of energy-efficient materials is an essential aspect of modern society, with efforts focused on reducing energy loss and conserving resources. A key element in the creation of energy-efficient electrical equipment, such as transformers, generators, and motors, is low-loss non-oriented electrical steel. In this regard, material design is a promising approach to improve the properties of non-oriented electrical steel. This paper presents an overview of material design for low-loss non- oriented electrical steel and its potential impact on energy conservation. The fundamental properties and processing of non-oriented electrical steel are discussed, highlighting the challenges and limitations faced in the production of low-loss steel. Furthermore, material design principles such as composition, microstructure, and processing are explored in detail, providing insight into how they can be tailored to optimize the properties of non-oriented electrical steel. Material design, this paper also discusses the characterization techniques that are employed to measure the properties of non-oriented electrical steel. The use of advanced techniques such as scanning electron microscopy, X-ray diffraction, and vibrating sample magnetometry is highlighted, showing how they can provide critical information about the microstructure and magnetic properties of non-oriented electrical steel and for energy efficiency and conservation, use electrical steel. The approach provides a promising strategy for the development of innovative materials that can contribute to the global goal of reducing energy consumption. The potential benefits of material design for non-oriented electrical steel extend beyond energy conservation and can have implications for the development of new technologies and industrial applications.</p>2023-02-27T00:00:00+00:00Copyright (c) 2023 International Journal of Metallurgy and Alloyshttps://materials.journalspub.info/index.php?journal=IJM&page=article&op=view&path%5B%5D=916Comparative Study of the Nature of Slag in the Formulation of Concrete Pavers2023-06-15T10:19:59+00:00Zakia Raiszakia.rais@usmba.ac.maN. H. Mtarfiazakia.rais@usmba.ac.maM. Taleb A.zakia.rais@usmba.ac.maW. Maherziczakia.rais@usmba.ac.ma<p><em>The steel mill generates about 8000 tons/year of slag by transforming scrap metal to produce more than 60000 tons/year of wire rod and steel reinforcing bars. These co-products are stored or used for backfill. With this almost inexhaustible slag deposit, Morocco has a valuable resource thanks to its high content of silicates, lime and metal oxides. This has led to the attempt to valorize it in the manufacture of paving stones. The tests were carried out with old SA and recent SR slag. After their physicochemical characterization, paving stones were made, using established formulations by substituting gravel by SA or SR slag. The cement to water volume ratio of the paving stones was optimized according to the performance of the paving stones by a statistical study. The study of the correlations between the parameters was carried out by the full factorial design and their analysis by the ANOVA. The results show that old slag is characterized by higher density, angularity, porosity, roughness, resistance to fragmentation and higher oxide composition than recent slag except for the elements iron and manganese. The statistical study showed that the nature of the old or recent slag and the W/C ratio have a significant influence on the quality of the paving stones. The best mechanical and durability properties of the paving stones were obtained for the old slag and a W/C ratio of 0.5.</em></p>2022-12-19T10:25:53+00:00Copyright (c) 2022 International Journal of Metallurgy and Alloyshttps://materials.journalspub.info/index.php?journal=IJM&page=article&op=view&path%5B%5D=910Nanocoating and Electrospray Techniques Use to Mitigation Corrosion Sculptures2023-06-15T10:19:59+00:00Rajesh Kumar Singhrks_jpujc@yahoo.co.inK. Hemarks_jpujc@yahoo.co.inMadhuram Ayushrks_jpujc@yahoo.co.in<p><em><span>The most sculptures of the world are created by the brass, bronze, iron, silver, gold and metalloid. They come in contact of corrosive pollutants to produce chemical, electrochemical and biochemical reactions and develop various form of corrosion like uniform corrosion, galvanic corrosion, pitting corrosion, stress corrosion and crevice corrosion. The corrosive gases CO<sub>2</sub>, NO<sub>2</sub> and SO<sub>2 </sub>concentrations increase in atmosphere rapidly after industrialization. The major contributors of these gases are burning of coal, thermal power and fusil foul. Pollutants corrode sculptures and tarnish interfacial looks. Corrosive gases change physical, chemical and mechanical properties of mterials. Pollutants occur in form of gases, liquids and particulates. The gaseous pollutants are carbon dioxide, nitrogen dioxide and sulphur dioxide, liquid pollutant acid rain and dust particles develop hostile environment for metallic sculptures. The corrosion of sculptures is a global problem. It is not fully control but their affects checked by the use of nanocoating and electrospray methods. Organic compound tetrahydro-dibenzo[7]annulene-5,11-disemicarbazone was synthesized in laboratory and it used as nanocoating. SiC coated on the surface of organic compound coated metal for the formation composite layer. The results of energy of activation, heat of adsorption, free energy, enthalpy and entropy indicated formation of chemical bonding with base metal. The gravimetric and potentiostatic polarization tools were applied for the calculation of corrosion rate of metal in presence of nitrogen dioxide. These compounds adsorption phenomenon were studied by the applications of Langmuir, Freundlich and Temkin equation. Corrosion rates of untreated and coated materials were used to calculate surface covering areas and coating efficiency. Complexation occurred on metal to verify by the values of thermal parameters, various isotherms and surface accommodation activities</span></em></p>2022-11-09T06:40:19+00:00Copyright (c) 2022 International Journal of Metallurgy and Alloyshttps://materials.journalspub.info/index.php?journal=IJM&page=article&op=view&path%5B%5D=905Review on Electrolytic Process by Refining the Metals2022-08-20T07:01:10+00:00Manoj Kumarmanojchauhancps@gmail.com<p>Electrolysis is a method of purifying impure metals. The crude metal that needs to be refined serves as the anode in an electrolytic cell while the metal that has been purified serves as the cathode. To ensure that the metal at the cathode is reduced extremely specifically, the electrode potential is chosen. Impurities are left behind in the electrolyte liquid as the metal is transferred from the<br />unrefined metal of the positive anode to the negative electrode. The element to be purified determines the electrolyte to use. Aqueous solutions are utilised for Cu, Ag, Au, and Pt, while molten salts are used for Na, Mg, Ca, and Al. The most typical metal ores have oxides or carbonates of the metals in them. Theoretically, the metal might be produced by electrolytically reducing the ores but in reality, reduced in the presence using carbon and is more frequently utilised since it is less expensive, even if this results in an unrefined metal and can have negative environmental effects. The preferable process is electrolysis when product purity is crucial. When copper is refined electrolytically, the anode and cathode are both unrefined copper, and the electrolyte is a liquid of copper sulphate and sulfuric acid. Only copper is decreased at the cathode due to careful selection of the electrode potential. The precious metals are also extracted from the anodic waste using electrolytic techniques. Ionic substances undergo electrolysis once an electric charge is delivered across them breaking them down into less complex substances. Metals are extracted and purified by electrolysis. When copper is electrolyzed, its dissolution causes the anode to lose mass while its deposit causes the cathode to acquire mass in order for oxidation to take place and electrons must be lost at the anode. Because electrons are acquired, reduction occurs at the cathode.</p>2022-08-20T07:00:23+00:00Copyright (c) 2022 International Journal of Metallurgy and Alloys
