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.
Journal ArticleDOI
Effect of extrusion parameters on microstructure and mechanical properties of Mg-7.5Gd-2.5Y-3.5Zn-0.9Ca-0.4Zr (wt%) alloy

TL;DR: In this article, the microstructure, texture and mechanical properties of the as-extruded alloys were investigated, and the results showed that the tensile yield strength of 345 MPa, ultimate tensile strength of 405 MPa and elongation to failure of 8.8%.
Journal ArticleDOI
Exceptional grain refinement in a Mg alloy during high pressure torsion due to rare earth containing nanosized precipitates
TL;DR: The influence of the nanosized rare earth (RE) containing precipitates on grain refinement during severe plastic deformation is investigated in detail through a study of high pressure torsion (HPT) processing of a solution treated and aged Mg-8.2Gd-3.8Y-1.4Zr (wt%) alloy.
Journal ArticleDOI
Evolution of microstructure and mechanical properties of an as-cast Mg-8.2Gd-3.8Y-1.0Zn-0.4Zr alloy processed by high pressure torsion
TL;DR: In this article, a novel Mg-82Gd-38Y-10Zn-04Zr alloy with high content of rare earth elements has been processed successfully by high pressure torsion (HPT) starting from an as-cast condition.
Journal ArticleDOI
Evolution of long-period stacking ordered structure and hardness of Mg-8.2Gd-3.8Y-1.0Zn-0.4Zr alloy during processing by high pressure torsion
TL;DR: In this article, high pressure torsion was performed at room temperature on a Mg-8.2Gd-3.8Y-1.4Zr (wt%) alloy containing long period stacking ordered (LPSO) phase with a 6.0 GPa pressure.
