An attempt is made to cover the whole of the topic of biodegradable magnesium (Mg) alloys with a focus on the biocompatibility of the individual alloying elements, as well as shed light on the degradation characteristics, microstructure, and mechanical properties of most binary alloys. Some of the various work processes carried out by researchers to achieve the alloys and their surface modifications have been highlighted. Additionally, a brief look into the literature on magnesium composites as also been included towards the end, to provide a more complete picture of the topic. In most cases, the chronological order of events has not been particularly followed, and instead, this work is concentrated on compiling and presenting an update of the work carried out on the topic of biodegradable magnesium alloys from the recent literature available to us.

“…As earlier stated in Section 2.3, the magnesium and aluminum elements can react in solid-state during the sintering process to form some intermediate compounds. This type of reaction in powder metallurgy is called the reaction-diffusion principle [38,39]. During the reactive sintering, the magnesium, aluminum and zinc element powders were heated to inter-diffuse into each other's lat-tices, and when a certain relative abundance was reached, the aluminum reacted with the magnesium to form the Mg 17 Al 12 intermetallic compound.…”

Porous magnesium alloy foams have gained tremendous interest from scientists because of their super lightweight, unique mechanical and physical properties. Despite numerous studies suggesting these advanced materials for structural and functional applications, their manufacturing processes remain poorly understood. In this paper, the porous Mg‐9 wt. %Al‐1 wt. % Zn alloy foam was prepared through the reactive sintering principle (i. e. the element metal powder reaction principle) by using the powder metallurgical method that is combined with a pore‐making agent. The chemical and phase compositions of the cell wall microstructure were investigated by X‐ray diffraction and scanning electron microscope equipped with energy dispersive spectrometer. The compressive properties of the foams were evaluated by quasi‐static compression testing. The results of the analysis reveal that low‐temperature sintering can produce qualitative magnesium alloy foams with good mechanical properties by taking advantage of the intermetallic/or intermediate compounds which are formed in the cell wall through metal elements powder diffusion and reaction. Particularly, the foam samples sintered at 380 °C for 12 h gave the best compressive properties owing to the alloy intermetallic contents and the relative density of the foams.

“…Solid diffusion processes are enabled by decreased particle size during milling because the gaps between the components are minimized and the defects are denser, and plastic deformation increases the surface energy. As a result, the more effective the diffusion mechanism between the grains, the higher the elemental consolidation in the composite [40].…”

The use of Mg-based compounds in solid-state hydrogen energy storage has a very high prospect due to its high potential, low-cost, and ease of availability. Today, solid-state hydrogen storage science is concerned with understanding the material behavior of different compositions and structure when interacting with hydrogen. Finding a suitable material has remained an elusive idea, and therefore, this review summarizes works by various groups, the milestones they have achieved, and the roadmap to be taken on the study of hydrogen storage using low-cost magnesium composites. Mg-based compounds are further examined from the perspective of artificial intelligence studies, which helps to improve prediction of their properties and hydrogen storage performance. There exist several techniques to improve the performance of Mg-based compounds: microstructure modification, use of catalytic additives, and composition regulation. Microstructure modification is usually achieved by employing different synthetic techniques like severe plastic deformation, high energy ball milling, and cold rolling, among others. These synthetic approaches are discussed herein. In this review, a discussion of key parameters and operating conditions are highlighted in a view to finding high storage capacity and faster kinetics. Furthermore, recent approaches like machine learning have found application in guiding the experimental design. Hence, this review paper also explores how machine learning techniques have been utilized to fasten the materials research. It is however noted that this study is not exhaustive in itself.
