“…It can be noticed from the microstructural comparison of both processing conditions (at 300 and 350 °C) that DRX is retarded or inhibited by dynamic precipitation during ECAP at 300 °C. Similar observations have been reported for WE54 (Mg-5Y-4Nd-0.5Zr, wt.%) alloy processed by uniaxial and plane strain compression at 300 °C under a strain rate of 10 -4 s -1 [30] and in ECAP-processed AZ91 (Mg-9Al-1Zn, wt.%) at 300 °C through 4 passes [37]. In this case, the precipitate particles act as a barrier to the grain boundaries migration through a pinning effect [30,37].…”

“…However, DRX is extremely retarded in the present alloy compared to the ECAP processed AZ91 (Mg-9Al-1Zn, wt.%) alloy under similar conditions (i.e. ECAP at 310 °C through 1-4 passes via route Bc) and undergoing dynamic precipitation of Mg17Al12 in which the fraction of DRX increased from 39 % after 1 pass up to 77 % after 4 passes [37]. Recently, it was found that the binary Mg-0.4Dy (wt.%) alloy shows retardation of DRX during plane strain compression test even at 400 °C under strain rate of 10 -4 s -1 where a complete DRX is often reported in Mg-based alloys [30,[57][58][59].…”

“…All alloys exhibit similar polarization behaviors during the measurements, as presented in figure 3. The cathodic curves exhibit linear tafel characteristics, implying the main reaction is hydrogen evolution reaction (HER) in 5 M HCl solution [17]. Apparent passivation zone can be observed in four titanium alloy without the evident transition from activation to passivation for the anodic curves.…”

The addition of interstitial elements often has a significant impact on the macroscopic performances of structural alloys. Here, we report a systematic study on the microstructure, corrosion behavior and mechanical properties of a series of as-cast Ti-0.3Mo-0.8Ni-xC (x = 0.09, 0.12 and 0.15 wt.%) alloys. A typical basket-weave microstructure appears in all specimens, characterized by the lamellar α-phase and intergranular retained β-phase without TiC precipitates existed in prior β grain boundary. Based on the electrochemical and immersion tests, doping with C element can significantly improve the corrosion resistance of TA10 alloys; with increasing the carbon content, the corrosion current density decreases from 13.58 to 3.54 μA·cm-2, the corrosion potential increases from -0.318 to -0.237 V vs. SCE, the corrosion rate reduces from 15 mm/a to 7.5 mm/a, along with an elevated pitting and crevice corrosion resistance. Moreover, the mechanical properties of TA10 alloys, such as the strength and hardness, can also be enhanced via C alloying. Our results indicate that the addition of interstitial elements should be a potential effective mean to accommodate the comprehensive performances of TA10 alloys.

“…The alloy cast with an ascending rolling temperature exhibited a DRX behavior, and the (0002) basal texture was weakened gradually. The hexagonal closed‐packed structure imputes poor ductility and formability because it may limit plastic deformation by slip dislocation, which leads to possible deformation mechanisms resulting from a non‐cubic symmetry 85,86 …”

Critical review on development of magnesium alloy as anode inMg‐Airfuel cell and additives in electrolyte

Summary This study aimed to provide a critical review of the magnesium‐air fuel cell (MAFC) system to provide readers with an overall comprehension of MAFC, which focuses on the modification of the magnesium anode and properties of saltwater as an electrolyte. Although MAFC is benign to the environment, it is well‐known for its challenging corrosion issue and by‐product deposition that affect its durability for commercialization and long‐term application. Since that MAFC is able to use seawater as electrolyte, it has great potential to be used as an alternative energy option for the marine sector. This journal will dissect the ability of MAFC to be used as a competitive alternative energy. Over the years, researchers have adopted several approaches, such as experimenting with different types of magnesium alloy and anode fabrication techniques, to tackle corrosion problems to alter the microstructure and mechanical properties of the anode in addition to applying a coating protection and using Mg‐based composite material. Furthermore, studies intriguingly and gradually focused on electrolyte formulation with different types of additives to address the debilitating precipitation issue and improve the discharge performance. Given the problems that arise in the system, currently, MAFC commercial products are only suitable as emergency back‐up power. In future work, an improved storage system for MAFC should be built to accommodate the precipitation products while maintaining the desired cell performance.
