A practical constitutive model for AZ31B Mg alloy sheets with unusual stress-strain response [PDF]

, 2019
Magnesium (Mg) and its alloys have been increasingly used in the automotive industry owning to their superior mechanical compared to other metals. Sheet forming of Mg alloys requires not only a good understanding of the materials but also an appropriate ...

Research progress in experimental and integrated calculations of high modulus magnesium based materials

Journal of Aeronautical Materials
Magnesium alloy is widely used in the aerospace field due to its low density，high specific strength，high damping and good thermal conductivity. However，its low elastic modulus limits its reliable application in large thin-walled components. Aiming at the

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 ...

Possibilities and Limitations of Scanning Electrochemical Microscopy of Mg and Mg Alloys [PDF]

Corrosion, 2014
Magnesium (Mg) and its alloys undergo corrosion at high rates in aqueous electrolytes of essentially any concentration, releasing copious amounts of hydrogen (H2) into the electrolyte, thereby making conventional scanning electrochemical microscopy (SECM) measurements difficult upon Mg.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Dislocation loop and irradiation-induced synergistic-competitive mechanism in Cu-rich precipitates: a phase-field study

Scientific Reports
Both irradiation and dislocations have been proposed as routes to rationally manipulate spatial distribution and micromorphology of precipitate. An interesting effect emerges in Fe–10at.%Cu–3at.%Mn–1.5at.%Ni–1.5at.%Al alloy due to the synergistic ...

Machine learning coupled with an improved exhaustive method-assisted design of a low cost Ti-Al-Cr-Fe-Si series titanium alloy

Materials & Design
In response to the high cost of titanium alloys and the low efficiency of traditional alloy design methods, this work combines machine learning (ML) with an improved exhaustion method (IEM) to accurately determine the relationship between alloy ...

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

FEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...
