“…The potential benefits of using magnesium in the aerospace industry led to several experiments throughout history where aircraft were constructed entirely with magnesium or magnesium as the base material. Notable examples include the military aircrafts Northrop XP-56, Lockheed F-80, Convair B-36, and Convair XC 99 [51].…”

“…Presently, with advancements in magnesium research, it is possible to manage these prevailing concerns with maintenance and repairs. However, performing these servicing activities will inevitably drive up its total cost of ownership [51]. Thus, despite significant improvements since the restrictions were first imposed, magnesium is still found mainly in engine-and transmission-related castings and landing gears only and not in external or structural applications [52].…”

“…These efforts cumulated to the discovery of less-flammable magnesium alloys, which opened the possibilities for them to be incorporated in passenger cabins. Accordingly, the Society of Automotive Engineers revised its standards, specifically AS8049C, in 2015 to allow magnesium alloys for aircraft seat construction if it complies with the Federal Aviation Administration requirements [24,51]. Another area with significant progress addresses magnesium's meager mechanical strength for engineering applications.…”

“…Another area with significant progress addresses magnesium's meager mechanical strength for engineering applications. Progress in this area is driven by the potential benefits of using magnesium in weight-sensitive applications, such as aircraft [51]. As a result, it led to the introduction of high-performance magnesium alloys like the Elektron 21, which has already received an Aerospace Material Specification (AMS 4429), and Elektron 675, which is reported to exhibit twice the strength of aluminum while only bearing half the weight of titanium [53].…”

Magnesium is a promising material. It has a remarkable mix of mechanical and biomedical properties that has made it suitable for a vast range of applications. Moreover, with alloying, many of these inherent properties can be further improved. Today, it is primarily used in the automotive, aerospace, and medical industries. However, magnesium has its own set of drawbacks that the industry and research communities are actively addressing. Magnesium’s rapid corrosion is its most significant drawback, and it dramatically impeded magnesium’s growth and expansion into other applications. This article reviews both the engineering and biomedical aspects and applications for magnesium and its alloys. It will also elaborate on the challenges that the material faces and how they can be overcome and discuss its outlook.

“…2 In addition, fine-grained forged Mg generally achieves higher mechanical properties than as-cast ones. 3,4 However, their high-temperature tensile properties are inferior due to their low melting temperatures depending on compositions. The rare earth metals (REMs) enhance the high-temperature strength of Mg base alloys.…”

This study examines the high-temperature tensile properties of AZ31 and AZ31-1.0Ca-0.2Ce alloys in different rolling directions. Tensile test results at 250 °C showed that the ductility of AZ31-1.0Ca-0.2Ce alloy increased threefold in the 90° perpendicular direction to rolling direction. Moreover, both strength and elongation values of AZ31-1.0Ca-0.2Ce alloy were higher than those of AZ31. Macro-texture measurements revealed that AZ31 and AZ31-1.0Ca-0.2Ce alloys showed strong and weakened basal texture in the rolling direction, respectively. The combined effect of secondary phases and texture weakening increased the high-temperature ductility (49%) of AZ31-1.0Ca-0.2Ce. In the rolling direction, yield (YS) and ultimate tensile strength of AZ31-1.0Ca-0.2Ce were obtained as 115 and 121 MPa, respectively. These values were higher than AZ31 alloy due to the stronger texture of the non-basal planes. The fracture surface of AZ31 samples proved that the rough and crack-dominated surface led to brittle fracture formation. However, fine-sized dimples resulted in a ductile fracture in AZ31-1.0Ca-0.2Ce samples.

Passive films are essential for the longevity of metals and alloys in corrosive environments. A great deal of research has been devoted to understanding and characterizing passive films, including their chemical composition, thickness, uniformity, thickness, porosity, and conductivity. Many characterization techniques are conducted under vacuum, which do not portray the true in‐service environments passive films will endure. Scanning electrochemical probe microscopy (SEPM) techniques have emerged as necessary tools to complement research on characterizing passive films to enable the in situ extraction of passive film parameters and monitoring of local breakdown events of compromised films. Herein, we review the current research efforts using scanning electrochemical microscopy, scanning electrochemical cell microscopy (or droplet cell measurements), and local electrochemical impedance spectroscopy techniques to advance the knowledge of local properties of passivated metals. The future use of SEPM for quantitative extraction of local film characteristics within in‐service environments (i.e., with varying pH, solution composition, and applied potential) is promising, which can be correlated to nanostructural and microstructural features of the passive film and underlying metal using complementary microscopy and spectroscopy methods. The outlook on this topic is highlighted, including exciting avenues and challenges of these methods in characterizing advanced alloy systems and protective surface films.
