“…The resulting material demonstrates a higher yield and ultimate strength. [ 62 ] In the bulk form, the electrical conductivity of a covetic is similar to that of the pure metal. Such conductivity is considered high given the high level of impurities (Fe, Ni, and S) that exist in covetic metals.…”

Advanced electrical conductors that outperform copper and aluminum can revolutionize our lives by enabling billions of dollars in energy savings and facilitating a transition to an electric mobility future. Nanocarbons (carbon nanotubes and graphene) present a unique opportunity for developing advanced conductors for electrical power, communications, electronics, and electric machines for the defense, energy, and automotive industries. Herein, the major research progress in the field of advanced nanocarbon-based and metalnanocarbon conductors is compiled. The benefits and drawbacks of advanced conductors are also elucidated with respect to conventional ones and their materials science, mechanical and physical properties, and characterization are discussed. Finally, several areas of future research for advanced electrical conductors are proposed.

“…Alloying has been widely used to overcome the above problems, and the known additive elements are indium, germanium, zinc, magnesium, thallium, tin, etc. [13][14][15][16][17][18]. The elements currently used to form alloys with aluminum are mainly Mg, Zn, Sn, and In, since they have higher hydrogen evolution potentials in an alkaline solution and lower melting points compared with aluminum [19][20][21].…”

In this work, Al-1Zn-0.1In-0.1Sn-0.5Mg-xMn (x = 0, 0.1, 0.2, 0.3) alloys are prepared and used as the anode of an Al-air battery (AAB). We use scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS) and optical microscopy (OM) to analyze the microstructures of the alloys. The hydrogen evolution rate, electrochemical performance (including polarization curves), electrochemical impedance spectroscopy (EIS), and battery performance of the samples are examined in the 4 M NaOH electrolyte. The experimental data display that the average grain size is significantly refined after adding manganese into the Al-1Zn-0.1In-0.1Sn-0.5Mg alloy, with a decrease in grain size from over 100 μm to about 10 μm. The improved activity of the aluminum anode in the AAB can be attributed to the introduction of manganese. The Al-1Zn-0.1In-0.1Sn-0.5Mg-0.1Mn alloy possesses the optimal overall performance with a lower self-corrosion rate (0.128 mL∙cm−2∙min−1), the highest working potential (1.630 V) and energy density (2415 mWh·g−1), a higher capacity (1481 mAh·g−1) and anodic utilization (49.75%).

“…The material must be allowed to various tests such as wear, impact test, and microstructural, before its implementation [21]. The mechanical characteristics of FGMs are typically based on the characteristics of the fabrication method and base material [22]. After fabrication, some machining processes are performed on the FGM to enhance its quality [23].…”

The characteristics of composite materials can be enhanced by using it as functionally graded composites (FGM). In this work, four-layer FGMs are produced by using aluminum, silicon carbide, and magnesium peroxide. The entire fabrication process has been performed through the sintering process, in which, the powder methodology is used to blend the particles of each material. During the fabrication of FGM, three parameters such as sintering time, sintering temperature and compacting pressure are considered. Four layers of the FGM are formulated as 100% of pure aluminum, 90%Al+ 10%SiC, 90%Al + 5%SiC+5%MgO 2 , and 85%Al + 5%SiC+10%MgO 2 respectively. The created FGMs have been analyzed to find out the mechanical, tribological and microstructural characteristics. The microstructure and worn-out surface of the FGM layers are analyzed via the scanning electron microscopy. In the mechanical analysis, the compressive strength and hardness characteristics of FGM material are investigated. The outcomes of the mechanical analysis are exhibited that the FGMs deliver the finest compressive strength,microhardness,and macro hardness as 315 Mpa, 1.26 Gpa,and 1.87 Gpa which are higher than the composite materials. Finally, Taguchi optimization has been performed to determine the optimum process parameters in terms of mechanical characteristics. The results of the Taguchi optimization exhibited that the mechanical characteristics of FGM are highly depending upon the sintering temperature and slightly on compacting pressure and sintering time.
