Bulk and Surface Low Temperature Phase Transitions in the Mg-Alloy EZ33A

Metals, 2020
Low-temperature phase transitions in the EZ33A Mg-cast alloy have been investigated. Based on the structure assessment of the alloy after annealing at 150 °C (1826 h) and at 200 °C (2371 h) a grain boundary wetting transition by a second solid phase was ...

Grain refinement driven by recrystallization after annealing nonequilibrium solidification microstructure of a deeply undercooled nickel alloy

Journal of Materials Research and Technology, 2023
Traditional recrystallization technology is based on recrystallization annealing after artificial plastic deformation. In the present study, we found that rapid solidification through deep undercooling can induce substantial plastic deformation and ...

Microstructural characterisation and thermal stability of an Mg-Al-Sr alloy prepared by rheo-diecasting [PDF]

, 2007
A commercial Mg-6Al-2Sr (AJ62) alloy has been prepared by a semisolid rheo-diecasting (RDC) process. The microstructure of the RDC alloy exhibits typical semisolid solidification features, i.e., 8.4 vol% primary α-Mg globules (23 μm in diameter), formed ...

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

FEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Turning a native or corroded Mg alloy surface into an anti-corrosion coating in excited CO2

Nature Communications, 2018
Despite their energy-efficient merits as promising light-weight structural materials, magnesium (Mg) based alloys suffer from inadequate corrosion resistance. One primary reason is that the native surface film on Mg formed in air mainly consists of Mg(OH)

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
