“…The Mg-10Y-2.5Sm alloy was investigated by Zhang et al [39] and it was reported that Mg24Y5 phase was distributed in α-Mg matrix uniformly and no phases contained Sm. The tensile properties, in the study, are attributed to the solid solution strengthening effect of Sm and strengthening by Mg24Y5.…”

Magnesium-rare earth based alloys are increasingly being investigated due to the formation of highly stable strengthening phases, activation of additional deformation modes and improvement in mechanical properties. Several investigations have been done to study the effect of rare earths when they are alloyed to pure magnesium and other Mg alloys. In this review, the mechanical properties of the previously investigated different magnesium-rare earth based binary alloys, ternary alloys and other higher alloys with more than three alloying elements are presented.

“…The same phenomenon can also be observed in Mg-8.31Gd-1.12Dy-0.38Zr [18]. Zhang et al conducted a comprehensive analysis on the mechanical properties of the Mg-10Y-2.5Sm alloy, attributing its exceptional tensile strength to the synergistic effects of solid solution strengthening and precipitation strengthening facilitated by Mg 24 Y 5 [19]. In recent years, numerous researchers have extensively investigated and documented the corrosion behavior of Mg-RE alloys.…”

Rare-earth magnesium alloys (Mg-RE) are gaining growing prominence across multiple industries due to their superior mechanical properties and enhanced formability compared to conventional magnesium alloys. β′ phase of Mg-RE alloys exhibits remarkable behavior in strengthening and enhancing corrosion resistance. However, the mechanical behaviors of some β′ phases themselves remain unexplored. Therefore, our objective is to identify the mechanical and thermomechanical properties of β′ phases. Herein, a theoretical study to investigate the structural, electronic, elastic and anisotropic properties of β′–Mg7RE phase from first-principle calculations is described. Besides, the melting temperature and Debye temperature of these intermetallic compounds are also predicted. The calculated results confirm the thermodynamic and mechanical stability of all β′–Mg7RE phases. Additionally, the calculated value of bulk modulus for all β′–Mg7RE phase exhibit similarity, with an approximate value of 38 GPa. The degree of anisotropy in the bulk modulus of the β′–Mg7RE phase is relatively lower compared to the shear and Young’s moduli. Among the β′ phase, β′–Mg7Lu exhibits the most pronounced anisotropy. Furthermore, the highest degree of Young’s and shear moduli anisotropy for all β′ phases are observed in the (001) plane. The value of the electron localization function between Mg and RE atoms ranges from 0.48 to 0.56. In more detail, the density of states (DOS) reveals that hybridization arises from strong interaction between the Mg–p states and RE–d states below the Fermi level. Indeed, the results will offer valuable insights into the influential factors on the mechanical properties of the β′ phase, contributing to a more comprehensive understanding of its performance and potential applications.

Electric vehicles are now proliferating based on technologies and components that in turn rely on the use of strategic materials and mineral resources. This review article discusses critical materials considerations for electric drive vehicles, focusing on the underlying component technologies and materials. These mainly include materials for advanced batteries, motors and electronics, lightweight structures, and other components specific to each vehicle type. Particularly strategic and widely used minerals and elements/structures for electric vehicles include nickel, cobalt, rare-earth minerals, lightweight and high strength steel alloys and underlying metals (e.g., magnesium and aluminum), carbon fiber, graphite and graphene, copper, and steel alloying materials. Additional key considerations include those around component and vehicle supply chains, repurposing and recycling vehicle components at end of vehicle life, and environmental and humanitarian considerations around the extraction and transport of the evolving set of materials needed for modern electric vehicle production.
