“…In actuality, high Al concentration Mg-Al alloys, such as AZ91, make up the majority of laser-based Mg-Al alloys [91]. This is because the addition of Al necessitates grain refinement of the alloys through superheating or inoculation, enhances castability (hence printability), and offers reinforcement through the solute and Mg17Al12 intermetallic phase [91][92]. Coming to the LPBF approach, Pawlak et al investigated the fabrication of AZ31 alloy-based material parts via LPBF approach and attributed to the low porosity level around 0.5% [93].…”

Magnesium and Aluminum alloys continue to be important in the context of modern and lightweight technologies. With the advancement of additive manufacturing (AM), components can be produced directly in a net shape, widen up the usage of magnesium and aluminum alloys as well as holding new ideas for the application of unique physical structures made feasible by 3D printing. Laser-based approach, one of the metal additive manufacturing (AM) methods, enables the formation of arbitrary 3D structures. With promising findings, research in this area is advancing quickly, bringing up a variety of potential applications in both the scientific and industrial sectors. Complex structures can now be manufactured easily utilizing AM technologies to meet the pre-requisite objectives like reduced part numbers, greater functionality, and lightweight, among others. AM has the ability to meet demands by lowering costs and speeding up the manufacturing process. Due to their popularity in numerous high-value applications, aluminum, and magnesium alloys are one of the key material systems being researched in the laser-based additive manufacturing approaches. The review here aims to comprehensively examine the additive manufacturing of magnesium and aluminum alloys, highlighting the influence of the laser-based additive manufacturing approach on the mechanical characteristics, microstructure, and tribological performance of magnesium and aluminum alloys.

“…Light alloys based on aluminium and magnesium are strong candidates for reducing the density of materials used in the transport industry. Their advantages include versatility in production and forming [ 2 , 3 , 4 , 5 , 6 ], a good mechanical strength-to-weight ratio [ 7 ], good formability, high fatigue strength [ 8 ], and a wide range of possible applications [ 9 ]. However, these alloys are very prone to corrosion phenomena, which occur naturally by reacting with oxygen and other gases or ions present in the environment to achieve a state of thermodynamic equilibrium of the material that reduces the internal energetics of the system.…”

Today’s environmental needs require the reduction of the weight of vehicles, thus reducing fuel consumption and associated emissions. For this reason, the use of light alloys is being studied, which, due to their reactivity, must be protected before use. In this work, the effectiveness of a hybrid sol-gel coating doped with various organic environmentally friendly corrosion inhibitors applied to an AA2024 lightweight aluminium alloy is evaluated. Some of the inhibitors tested are pH indicators, acting as both corrosion inhibitors and optical sensors for the surface of the alloy. Samples are subjected to a corrosion test in a simulated saline environment and characterised before and after the test. The experimental results regarding their best inhibitor performance for their potential application in the transport industry are evaluated.

Al/Mg bimetal was prepared by lost foam solid-liquid compound casting, and the effects of mechanical vibration on the filling and solidification behavior, microstructure and performance of the bimetal were investigated. Results show that the mechanical vibration has a remarkable influence on the filling and solidification processes. It is found that after mechanical vibration, the filling rate increases and the filling rate at different times is more uniform than that without vibration. In addition, the mechanical vibration also increases the wettability between liquid AZ91D and A356 inlays. The mechanical vibration reduces the horizontal and vertical temperature gradient of the casting and makes the temperature distribution of the whole casting more uniform. Compared to the Al/Mg bimetal without vibration, the shear strength is improved by 39.76% after the mechanical vibration is applied, due to the decrease of the inclusions and Al 12 Mg 17 dendrites, and the refinement and uniform distribution of the Mg 2 Si particles in the interface of the Al/Mg bimetal.
