Laser additive manufacturing of biodegradable magnesium alloy WE43: A detailed microstructure analysis.
Florian Bär,Leopold Berger,Lucas Jauer,Güven Kurtuldu,Robin Schäublin,Johannes Henrich Schleifenbaum,Jörg F. Löffler +6 more
TL;DR: This study is the first to report in detail on the microstructure development of the established magnesium alloy WE43 fabricated by the additive manufacturing process of Laser Powder Bed Fusion (LPBF), which presents unique microstructural features which originate from the laser-melting process.

Metastable quasicrystal-induced nucleation in a bulk glass-forming liquid.
TL;DR: A unique Mg-based alloy composition in the Mg–Zn–Yb system is presented which exhibits bulk metallic glass, metastable icosahedral quasicrystals, and crystalline approximant phases in the as-cast condition and sheds light on the competition between metastable and stable crystals.
Solidification of Metallic Alloys: Does the Structure of the Liquid Matter?
TL;DR: In this article, it was shown that Icosahedral Short Range Order (ISRO) of atoms in the liquid could possibly explain the large nucleation undercoolings measured in metallic alloys by Turnbull and Fisher.
Influence of icosahedral short range order on diffusion in liquids: A study on Al-Zn-Cr alloys
TL;DR: In this article, the effect of Cr addition on Zn diffusion in liquid Al-Zn-Cr alloys was investigated, and it was shown that Cr indeed slows down the diffusion and mobility of Zn atoms, an effect which reinforces the hypothesis of ISRO induced by Cr.
