Mechanical Alloying of Mg-Be.

Journal of the Japan Society of Powder and Powder Metallurgy, 2000
Mg-10mass%Be, Mg-20mass%Be, Mg-30mass%aBe and Mg-40mass%Be alloys were synthesized by mechanical alloying (MA) of elementary Mg and Be powders for 720 ks milling under 66 kPa argon gas atmosphere using by a planetary ball milling. In the case of Mg-10mass%Be, the big blocks occurred due to the joining of the MA powders. Others showed fine powders after

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Texture Evolution of AZ31 Magnesium Alloy Sheet at High Strain Rates [PDF]

, 2010
In the current contribution the mechanical behaviour at high strain rates of AZ31 magnesium alloy sheet is studied. Uniaxial deformation properties were studied by means of tensile split Hopkinson pressure bar (SHPB) at different temperatures.

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 ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Process Mechanics and Surface Integrity Induced by Dry and Cryogenic Machining of AZ31B-O Magnesium Alloy [PDF]

, 2013
The corrosion resistance of magnesium alloys depends mainly on its surface integrity. Previous experimental studies have shown that machining can induces small (nano-scale) grain size, compressive residual stresses and basal plane crystallographic ...
