“…As reported by Y.X. Qiao [64], the medium-frequency capacitive arc is caused by the diffusion of medium in porous solid film on metal surface. The middle-frequency capacitive arc of both cast and SS Mg-9Li alloys prove the appearance of surface films on both samples.…”

Cast Mg-9Li alloy was successfully solid-solution (SS) treated via heating at 575 °C for 4.5 h and rapidly quenched with ice-water mixture. The mechanical property and corrosion resistance of the SS alloy were simultaneously improved. Rapid bcc/hcp phase transition of the alloy occurred during the quenching process, creating the newly precipitated needle-like fine α-Mg phase, uniformly distributed in the β-Li phase matrix. Dramatic grain refinement and uniform distribution of the α-Mg phase, as well as the massively increased α/β phase interfaces, are factors leading to the improved mechanical property of the SS alloy. Meanwhile, due to the modified duplex-phase structure, the SS alloy has a uniform corrosion-resistant surface film on the β-Li phase, which completely covers the entire alloy surface and efficiently protects the substrate. In addition, the SS alloy has fewer difference in the elements concentration and corrosion activity of the duplex phases, which reduces the pitting sensitivity and improves the corrosion resistance of the alloy matrix. The findings in this binary Mg-Li alloy can also serve as a benchmark for other more practical and complicated Mg-Li alloys.

This study proposes MnO 2 thin nanosheets assembled microspheres with oxygen vacancies and preinsertion of Na ions (NaMnO 2−x ) as highly capable supercapacitor electrodes. The NaMnO 2−x electrode can reach a stable potential window of 1.2 V without oxygen evolution reactions in threeelectrode configuration. The voltage window of the assembled aqueous ASC device can be expanded to 2.4 V (1 M Na 2 SO 4 ) by using NaMnO 2−x electrode and activated carbon electrode as positive and negative electrodes, respectively. The NaMnO 2−x electrode delivers a good specific capacitance of 215 F·g −1 at current density of 1 A·g −1 . It displays high-rate capability and an excellent cycling stability, maintaining 95.5% of its initial specific capacitance at 2 A·g −1 after 2500 cycles. The ASC device shows a high energy density and power density of 28.56 W·h·kg −1 and 1246 W·kg −1 , respectively, at a current density of 1 A·g −1 . OPEN ACCESS RECEIVED

“…The impedance data were analyzed using the equivalent circuit shown in Figure 8. The use of a constant phase element (CPE) was necessary [29][30][31] due to the distribution of relaxation times resulting from heterogeneities at the electrode surface. The CPE was used for the description of a frequency-independent phase shift between an applied AC potential and its current response [32], and has been extensively investigated [29,33].…”

X-ray diffraction (XRD), scanning electron microscope (SEM), immersion, electrochemical, and tensile tests were employed to analyze the phase constitution, microstructure, corrosion behaviors, and tensile properties of a Ti-6Al-4V alloy and a newly-developed low cost titanium alloy Ti-4Al-2V-1Mo-1Fe. The results showed that both the Ti-6Al-4V and Ti-4Al-2V-1Mo-1Fe alloys were composed of α and β phases. The volume fractions of β phase for these two alloys were 7.4% and 47.3%, respectively. The mass losses after 180-day immersion tests in 3.5 wt.% NaCl solution of these alloys were negligible. The corrosion resistance of the Ti-4Al-2V-1Mo-1Fe alloy was higher than that of the Ti-6Al-4V alloy. The tensile tests showed that the Ti-4Al-2V-1Mo-1Fe alloy presented a slightly higher strength but a lower ductility compared to the Ti-6Al-4V alloy.
