Elastic properties of an Mg-Zn-Y alloy single crystal with a long-period stacking-ordered structure
TL;DR: In this paper, the elastic properties of an Mg85Zn6Y9 (at.%) alloy single crystal with a long-period stacking-ordered (LPSO) structure, synchronized with periodic enrichment of Zn and Y atoms, were investigated, the properties having remained unclear because of the difficulty in growing large single crystals.

Altered ageing behaviour of a nanostructured Mg-8.2Gd-3.8Y-1.0Zn-0.4Zr alloy processed by high pressure torsion
W.T. Sun,Xiao Guang Qiao,Mingyi Zheng,Chao Xu,Shigeharu Kamado,Xiaojun Zhao,Houwen Chen,Nong Gao,Marco J. Starink +8 more
TL;DR: In this paper, the ageing behavior of a nanostructured Mg-8.2Gd-3.8Y-1.4Zr (wt.%) alloy produced by solution treatment followed by high pressure torsion (HPT) was systematically investigated using hardness testing, high resolution high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM), elemental mapping, X-ray diffraction (XRD) and XRD line broadening analysis.

Magnesium: Properties — applications — potential
B.L Mordike,T Ebert +1 more
TL;DR: Magnesium is the lightest of all metals used as the basis for constructional alloys and it is this property which entices automobile manufacturers to replace denser materials, not only steels, cast irons and copper base alloys but even aluminium alloys by magnesium based alloys as discussed by the authors.

Rapidly Solidified Powder Metallurgy Mg97Zn1Y2Alloys with Excellent Tensile Yield Strength above 600 MPa
TL;DR: In this paper, the RS P/M alloys exhibited excellent elevated-temperature yield strength that was 510 MPa at 423 K. The specific tensile yield strength was four times as high as that of a commercial AZ91-T6 alloy, and was higher than those of conventional titanium (Ti-6Al-4V) and aluminum (7075-T 6) alloys.
