Temperature dependency of slip and twinning in plane strain compressed magnesium single crystals
Adrien Chapuis,Julian H. Driver +1 more
TL;DR: In this paper, the critical resolved shear stresses (CRSSs) of slip and twinning in magnesium crystals, as a function of temperature, under conditions of imposed strains, were characterized by systematic electron backscatter diffraction orientation maps.

A crystal plasticity model for hexagonal close packed (HCP) crystals including twinning and de-twinning mechanisms
TL;DR: In this paper, a physics-based twinning and de-twinning (TDT) model is proposed for polycrystalline plastic deformation, which is characterized by four deformation mechanisms corresponding to twin nucleation, twin growth, twin shrinkage, and retwinning.

Structural evolutions of metallic materials processed by severe plastic deformation
TL;DR: In this paper, a comprehensive review on important micro-structural evolutions and major microstructural features induced by SPD processing in single-phase metallic materials with face-centered cubic structures, body-centered cylindrical structures, and hexagonal close-packed structures, as well as in multi-phase alloys is provided.

Influence of texture on Hall–Petch relationships in an Mg alloy
TL;DR: In this paper, the influence of changes in crystallographic texture on the Hall-Petch (H-P) relationship for an Mg alloy was investigated, and the texture variations were facilitated by changing the uniaxial tensile loading orientation with respect to the normal direction of the rolled Mg plate.

Phenomenological crystal plasticity modeling and detailed micromechanical investigations of pure magnesium
Jing Zhang,Shailendra P. Joshi +1 more
TL;DR: In this paper, a single crystal plasticity model for pure Mg incorporating slip and deformation twinning is presented, which uses the basic framework of Kalidindi (1998), but proposes constitutive descriptions for the slip and twin evolution and their interactions that are motivated by experimental observations.

Magnesium: Properties — applications — potential
B.L Mordike,T Ebert +1 more
TL;DR: Magnesium is the lightest of all metals used as the basis for constructional alloys and it is this property which entices automobile manufacturers to replace denser materials, not only steels, cast irons and copper base alloys but even aluminium alloys by magnesium based alloys as discussed by the authors.

A theory of the yielding and plastic flow of anisotropic metals
TL;DR: In this article, a theory is suggested which describes the yielding and plastic flow of an anisotropic metal on a macroscopic scale and associated relations are then found between the stress and strain-increment tensors.

Structure of Metals
TL;DR: The first serious application of the microscope to the study of metallic structure was made in 1864 by Dr. H. Sorby, of Sheffield, but the lead then given was not followed for nearly a quarter of a century as mentioned in this paper.

Kinetics of flow and strain-hardening☆
H. Mecking,U.F. Kocks +1 more
TL;DR: In this paper, a phenomenological model is proposed to incorporate the rate of dynamic recovery into the flow kinetics, which has been successful in matching many experimental data quantitatively, and it has been shown that the proportionality between the flow stress and the square root of the dislocation density holds, to a good approximation, over the entire regime; mild deviations arc primarily attributed to differences between the various experimental techniques used.

Overview no. 42 Texture development and strain hardening in rate dependent polycrystals
R.J. Asaro,Alan Needleman +1 more
TL;DR: In this article, a rate dependent constitutive model is developed for polycrystals subjected to arbitrarily large strains, and the model is used to predict deformation textures and large-strain strain hardening behavior following various stressstrain histories for single phase f.c. aggregates that deform by crystallographic slip.
