Plastic anisotropy and the role of non-basal slip in magnesium alloy AZ31B
Sean R. Agnew,Ozgur Duygulu +1 more
TL;DR: In this paper, a combination of experimental and simulation techniques were used to investigate the plastic behavior of wrought magnesium alloy and found that an increased activity of non-basal dislocations provides a self-consistent explanation for the observed changes in the anisotropy with increasing temperature.

Twinning and the ductility of magnesium alloys Part I: “Tension” twins
TL;DR: In this article, a series of tensile test results are reported for the common wrought alloy AZ31 and a simple constitutive model is employed to argue that View the MathML source twinning (which gives extension along the c-axis) can increase the uniform elongation in tensile tests.

Hardening evolution of AZ31B Mg sheet
TL;DR: In this article, the monotonic and cyclic mechanical behavior of O-temper AZ31B Mg sheet was measured in large-strain tension/compression and simple shear.
Journal ArticleDOI
On the role of non-basal deformation mechanisms for the ductility of Mg and Mg–Y alloys
TL;DR: In this paper, the authors focused on understanding the mechanisms for ductility improvement by microstructure analysis, texture analysis and slip trace analysis based on electron backscatter diffraction and transmission electron microscopy.
Journal ArticleDOI
Enhanced deformation mechanisms by anisotropic plasticity in polycrystalline Mg alloys at room temperature
TL;DR: In this article, the authors present room-temperature deformation mechanisms in polycrystalline Mg alloys and show that dislocation slip of basal and prismatic alloys can occur nearly at the same ease when the basal planes are tilted in such a way that the Schmid-factor ratio (equivalent to the critically resolved shear stress (CRSS) ratio) of prismatic to basal slip is larger than a value ranging from 1.5 to 2.

Slip, twinning, and fracture in hexagonal close-packed metals
TL;DR: The role of deformation twinning in fracture of hexagonal close-packed metals is reviewed from a theoretical point of view in this paper, where strength and ductility are correlated with the intrinsic physical and metallurgical variables.
Journal ArticleDOI
The onset of twinning in metals: a constitutive description
TL;DR: In this article, a constitutive expression for the twinning stress in BCC metals is developed using dislocation emission from a source and the formation of pile-ups, as rate-controlling mechanism.

Thermophysical properties of materials
TL;DR: In this paper, the authors consider the thermal properties of harmonic lattice vibrations in real crystals and atomic vibrations in defect lattices, as well as the properties of anisotropic and polycrystalline materials.
