A high-strength low-rare-earth-alloyed Mg− 3.5 Sm− 2Yb− 0.6 Zn− 0.4 Zr alloy was
processed by an ingot metallurgy process with hot-extrusion followed by artificial aging. The …

Ultrahigh strength is achieved in low-cost Mg-4Sm-0.6 Zn-0.4 Zr alloy by a traditional
extrusion process, with tensile yield strength over 450 MPa, which exceeds the majority of …

Abstract The Mg–12Gd–3Y–0.6 Zr (GW123, wt.%) alloy was prepared by cast, and thermo-
mechanically treated by single and secondary hot extrusion techniques. The microstructure …

Abstract Mg-xGd-3Y-yNd-0.5 Zr alloys (x= 6, 8, 10; y= 0.5, 1 wt%) were prepared by hot
extrusion, pre-annealing and ageing treatments. After hot extrusion, the alloys exhibit a …

A remarkably high tensile yield strength of 445MPa is obtained in a Mg–14Gd–0.5 Zr (wt.%)
alloy when this alloy is prepared by the combined processes of hot extrusion, cold rolling …

Abstract A high strength Mg-11.7 Gd-4.9 Y-0.3 Zr (wt%) alloy with a weak tension-
compression yield asymmetry has been successfully developed by pre-deformation …

The microstructure evolution and mechanical properties of as-extruded Mg-11.5 Gd-4.5 Y-
0.3 Zr (wt%) alloy with Zn and Nd additions were investigated. The addition of Zn inhibits the …

In this study, an ultra-high yield strength (~ 417 MPa) and moderate ductility (~ 12.9%) was
obtained in Mg–8.2 Gd–3.8 Y–1.0 Zn–0.4 Zr (wt%) alloy through a method of decreased …

Extraordinary high-strength Mg–1.8 Gd–1.8 Y–0.7 Zn–0.2 Zr alloy has successfully been
fabricated by an ingot metallurgy process with hot extrusion followed by aging. The sample …

Abstract Effects of 0.5 wt% La addition on microstructures and mechanical properties of a
traditional hot-extruded Mg–9Gd–3Y–0.5 Zr alloy were thoroughly investigated in this work …
