Mechanical properties of Mg-8Gd-3Y-0.5Zr alloy with bimodal grain size distributions

Journal of Magnesium and Alloys, 2017
The Mg-Gd-Y-Zn-Zr alloys are representational and potential age-hardening systems as reported in the past ten years, but their mechanical properties are still dependent on the grain size and its distribution. The effect of bimodal structure on mechanical

Solid state recycling of Mg–Gd–Y–Zn–Zr alloy chips by spark plasma sintering

Journal of Magnesium and Alloys, 2020
The consolidation Mg–Gd–Y–Zn–Zr billets containing long period-stacking ordered (LPSO) phase were recycled from the metal chips through the spark plasma sintering (SPS) process, which achieves the effective metallurgical bonding between metal chips.

Elevated-temperature impact toughness of Mg–(Gd, Y)–Zr alloy [PDF]

, 2013
The Charpy impact results for Mg–10Gd–3Y–0.5Zr and Mg–11Y–5Gd–2Zn–0.5Zr alloys at various temperatures showed that Mg–10Gd–3Y–0.5Zr was more sensitive to temperature. The increase in impact toughness with temperature was related to the blunt crack-tip at

Work functions, ionization potentials, and in-between: Scaling relations based on the image charge model [PDF]

, 2002
We revisit a model in which the ionization energy of a metal particle is associated with the work done by the image charge force in moving the electron from infinity to a small cut-off distance just outside the surface.
