The splitting of water through electrocatalysis offers a sustainable method for the production
of hydrogen. In alkaline electrolytes, the lack of protons forces water dissociation to occur …

Poor room temperature (RT) ductility is an inherent disadvantage of magnesium (Mg) alloys,
which limits their wide application. Grain refinement is an accepted method to improve …

Grain refinement can significantly enhance the strength of metallic materials, but usually at
the sacrifice of ductility. Here we report that refinement of magnesium grains can not only …

Multicomponent alloys of the Fe-Mn-Co-Cr-Ni family with face-centered cubic (fcc) structure
exhibit many excellent properties. However, they usually show limited yield strength, which …

Grain boundary (GB) segregation can drastically affect both the thermal stability and fracture
strength of nanocrystalline metals. Underlying physics of the correlation between the above …

Equal-channel angular pressing (ECAP) technique has emerged as a desirable strategy to
fairly improve the properties of magnesium (Mg) alloys. However, poor workability of Mg …

Obtaining ultra-high strength in commercial ZK60 wrought alloys is rather difficult by
conventional processes due to their limited precipitation hardening. In this work, we …

Abstract The Mg-12Gd-2Er-0.4 Zr (GE122K) is fabricated by double extrusion, and the
effects of grain refinement and precipitate evolution on the mechanical performance of the …

The effects of four different hot extrusion processes on the microstructure, texture, and
mechanical properties of Mg–5Li–3Sn–2Al–1Zn alloys were investigated with the help of …

Here we report in-situ TEM observations on interaction between dislocations and β′
phases in aged Mg–Gd alloys. The slipping dislocations squash into the interface and bow …
