“…On the other hand, grain growth during sintering of powder metallurgy consolidated products remains a major problem to obtain MMNCs with desired properties [4]. The use of solid-state processing methods such as mechanical alloying [5][6][7][8] permitted the development of nanocomposite materials having large volume fraction of nanosize reinforcement phase homogeneously dispersed in a nanostructured matrix. However, the use of conventional sintering methods such as hot pressing, high-temperature extrusion, and hot isostatic pressing to consolidate these materials often results in grain growth which affects the properties of the end product.…”

Metal matrix nanocomposites (MMNCs) are those metal matrix composites where the reinforcement is of nanometer dimensions, typically less than 100 nm in size. Also, it is possible to have both the matrix and reinforcement phases of nanometer dimensions. The improvement in mechanical properties of MMNCs is attributed to the size and strength of the reinforcement as well as to the fine grain size of the matrix. Spark plasma sintering has been used extensively over the past years to consolidate wide range of materials including nanocomposites and was shown to be effective noneconventional sintering method for obtaining fully dense materials with preserved nanostructure features. The objective of this work is to briefly present the spark plasma sintering process and review published work on spark-plasma-sintered metals and metal matrix nanocomposites.

“…In the composite, reinforcement clusters led to an increased content of ball-milled aluminum particles and a substantial increase in fracture work. The presence of micro cracks in Al particles is often associated to reinforcement cluster and contributed to the sudden drop due to failure strain [38].…”

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.

“…The failure strain (ductility) improvement in Mg-(5.6Ti+3Al)-2.5B 4 C composite attributes to the following factors pertaining to the presence of nano-B 4 C particulates in Mg matrix. Available literature on nanocomposites shows that the nanoparticles provide sites for opening the cleavage cracks ahead of advancing crack front [11,12,31] and alters the local effective stress state from plane strain state to plane stress state in the neighbor-hood of crack tip [32]. This dissipates the stress concentration which would otherwise exist at the crack front [11,12,32].…”
