“…167 When Al−Mg−Sc alloys are produced using severe deformation methods only modest improvements over ordinarily fabricated material are achieved. 168 RE additions to Mg-based alloys are known to improve ductility, refine grain size and weaken recrystallisation textures and improve fatigue performance, although additions of RE elements other than Sc are more commonly reported.

Despite its excellent elemental properties, lightweight nature and good alloying potential, scandium has received relatively little attention in the manufacturing community. The abundance of scandium in the Earth's crust is quite high. It is more abundant than silver, cobalt, lead and tin. But, because scandium is so well dispersed in the lithosphere, it is notoriously difficult to extract in commercial quantities-hence low market availability and high cost. Scandium metallurgy is still a largely unexplored field-but progress is being made. This review aims to summarise advances in scandium metallurgical research over the last decade. The use of scandium as a conventional minor addition to alloys, largely in structural applications, is described. Also, more futuristic functional applications are discussed where details of crystal structures and peculiar symmetries are often of major importance. This review also includes data obtained from more obscure sources (especially Russian publications) which are much less accessible to the wider community. It is clear that more fundamental research is required to elevate the status of scandium from a laboratorybased curiosity to a mainstream alloying element. This is largely uncharted territory. There is much to be discovered.

“…Wirtz et al [4] and Roder et al [5] have pointed out that the Al-Mg-Sc alloys exhibit a higher resistance against fatigue crack nucleation in comparison with the commercial 6013-T6 alloy. In their literature, however, the relationship between the microstructure and mechanical response has not been clearly discussed.…”

“…It is well accepted that small additions of rare earth elements are of great importance to improve the mechanical properties of aluminum alloys and provide extended alloying capabilities. Over the past several years, in the case of aluminum alloys rare earth Scandium (Sc) has been most commonly studied as beneficial microalloying element [5], suggesting the beneficial effects on mechanical properties that associated with remarkably grain refinement, dynamic recrystallization controlling and also fatigue as proposed by Wirtz et al [6]. However, the applications of Sccontaining alloys are extremely restricted due to the high cost of Sc addition.…”
