Superplastic Behavior of AZ31 Processed by ECAP

Procedia Materials Science, 2015
AbstractMagnesium base alloys have reached an important development as structural materials the last years due to its good strength/weight relationship. On the other hand, superplastic forming has also acquired a technological interest in the last time, due to the possibility of achieving complex geometries in only one forming step, with competitive ...

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 ...

Texture softening in a rare earth elements-containing AZ31 magnesium alloy during hot compression deformation

Journal of Materials Research and Technology, 2022
The effect of rare element (RE) addition on the softening behavior of an AZ31 alloy was examined during hot compression. It was revealed that the RE-containing alloy (AZ31-1RE) exhibits a lower flow stress at deformation temperatures above the transition

Texture Evolution of AZ31 Magnesium Alloy Sheet at High Strain Rates

, 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.

Imagined Integration: The Logics of Japanese Immigrant Integration Policy

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT As governments develop immigrant integration policies, they draw on and express conceptions about what successful integration looks like—what we call “imagined integration.” Yet this imagination likely displays variation that matters for implementation: integration policymaking is increasingly multilevel as it involves subnational layers of ...
