Microstructure and mechanical properties of extruded and rolled Mg–Y–Zn–Ni–Co alloy

Journal of Materials Research and Technology, 2023
The as-cast Mg–2Y-0.5Zn-0.5Ni-0.5Co alloy (MYZNC, at%) underwent composite hot working, extrusion and rolling to further improve the mechanical properties, and the corresponding microstructure and mechanical properties were also investigated.

Substitution of Ni for Zn on microstructure and mechanical properties of Mg–Gd–Y–Zn–Mn alloy

Journal of Magnesium and Alloys, 2017
This study analyzes the effect of substitution of Ni for Zn on microstructure and mechanical properties of Mg–Gd–Y–Zn–Mn alloy. Our results show that the volume fraction of Mg5(Gd, Y) and (Mg, Zn)3RE phase decreased and LPSO phase increased with more ...

Rapid corrosion rates and high mechanical properties of as-extruded Mg–Er–Ni alloys by introducing LPSO and γʹ phases

Journal of Materials Research and Technology, 2023
The Mg–Er–Ni alloy with comparable strength and solubility was prepared by controlling the Ni content. The mechanical properties and corrosion mechanism of alloys with long-period stacking ordered (LPSO) phase, as well as those with both LPSO and γʹ ...

Polytypes of long-period stacking structures synchronized with chemical order in a dilute Mg-Zn-Y alloy

, 2011
A series of structural polytypes formed in an Mg-1at.%Zn-2at.%Y alloy has been identified, which are reasonably viewed as long-period stacking derivatives of the hcp Mg structure with alternate AB stacking of the close-packed atomic layers.

Systems Biology and Pangenome of Salmonella O-Antigens. [PDF]

, 2019
O-antigens are glycopolymers in lipopolysaccharides expressed on the cell surface of Gram-negative bacteria. Variability in the O-antigen structure constitutes the basis for the establishment of the serotyping schema. We pursued a two-pronged approach to

Tuning the LPSO-dominated microstructure for strength increment of wire arc-directed energy deposited VWZ104K magnesium alloy

Review of Materials Research
Long-period stacking ordered (LPSO) phase endows Mg-Gd-Y-Zn-Zr magnesium alloys with improved mechanical property. Here, the Mg-10Gd-4Y-1Zn-0.5Zr (wt.%) alloy is fabricated by wire arc-directed energy deposition (WA-DED), and the microstructure dominated

Achieving high strength-ductility synergy in a Mg97Y1Zn1Ho1 alloy via a nano-spaced long-period stacking-ordered phase

Journal of Magnesium and Alloys, 2023
Achieving high strength in Mg alloys is usually accompanied by ductility loss. Here, a novel Mg97Y1Zn1Ho1 at.% alloy with a yield strength of 403 MPa and an elongation of 10% is developed.

Effect of heat treatment on microstructure and mechanical properties of Mg-Gd-Y-Zn-Zr alloy

Journal of Materials Research and Technology
This paper examined the effects of heat treatment on the microstructure evolution and mechanical properties of the Mg-8Gd-3Y-1.5Zn-0.6Zr (VWZ832K) alloy. After solution treatment, it was discovered that the alloy's LPSO phase had altered from 18R-LPSO to
