TLDR
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.About:

The texture and anisotropy of magnesium–zinc–rare earth alloy sheets
TL;DR: In this article, the rolling textures of six magnesium alloys containing different levels of zinc and rare earth (RE, e.g. mischmetal or Y) additions are examined. And the influence of texture on the mechanical response is investigated.

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
Role of {10–12} twinning characteristics in the deformation behavior of a polycrystalline magnesium alloy
TL;DR: In this paper, the activation of specific twin variants depending on the strain path induced a significant difference in twinning characteristics, such as twin morphology, volume fraction of twins with strain, and twin texture, and consequently gave rise to a totally different effect on the deformation.
Journal ArticleDOI
Orthotropic yield criterion for hexagonal closed packed metals
TL;DR: In this article, a macroscopic orthotropic yield criterion, which can describe both the anisotropy of a material and the yielding asymmetry between tension and compression, is introduced.
Journal ArticleDOI
Effect of rare earth additions on microstructure and texture development of magnesium alloy sheets
TL;DR: In this paper, a relationship is drawn between the weak textures and the appearance of deformation bands with compression and double twins during rolling and a grain growth restriction during annealing of the sheets.

A self-consistent anisotropic approach for the simulation of plastic deformation and texture development of polycrystals : application to zirconium alloys
TL;DR: In this paper, a visco-plastic self-consistent (VPSC) anisotropic approach for modeling the plastic deformation of polycrystals, together with a thorough discussion of the assumptions involved and the range of application of such approach is presented.

Limit strains in the processes of stretch-forming sheet metal
TL;DR: In this paper, a theoretical analysis of the process of the generation of the groove based on anisotropic plasticity theory is presented, and the system of equations derived was solved numerically with the aid of a computer, which enabled the limiting strain of the sheet metal to be determined as a function of the material.

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.
