Strengthening of αMg and long-period stacking ordered phases in a Mg-Zn-Y alloy by hot-extrusion with low extrusion ratio
TL;DR: In this paper , an as-cast sample and two hot-extruded samples with different extrusion ratios (R) of Mg97Zn1Y2 alloy containing the HCP α matrix (αMg) and the long-period stacking ordered phase (LPSO) of about 25vol%, were used in tensile deformation in situ neutron diffraction experiments, to elucidate the effects of uniquely different microstructural evolutions in αMg and LPSO with varying the R value to the mechanical properties.

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.
