In this paper, the relationship between anisotropic mechanical properties and corresponding microstructure evolution of wrought magnesium alloys is critically reviewed. Experimental observations strong anisotropy (including strength differential effect) induced by texture twinning are discussed under different loading conditions (i.e., monotonic, cyclic multiaxial loading). An accurate constitutive model essential to describe responses predict forming performance considering engineering...
Molecular dynamics (MD) simulation is employed to investigate the deformation behavior under various loading paths and strain rates of nanocrystalline magnesium (NC Mg) with [0001] texture. Atomic-scale structural evolution NC Mg was performed uniaxial biaxial loadings. In tension process, compression twins basal slip dominate, while process dominated by twins. The activation mechanism twinning highly sensitive path grain orientation. Meanwhile, effect rate on investigated. It found that...
A Fe-34.5 wt % Mn-0.04 C ultra-high Mn steel with a fully recrystallised fine-grained structure was produced by cold rolling and subsequent annealing. The exhibited excellent cryogenic temperature properties enhanced work hardening rate, high tensile strength, uniform elongation. In order to capture the unique mechanical behaviour, constitutive model within finite strain plasticity framework based on Hill-type yield function established standard Armstrong-Frederick type isotropic hardening....
Advanced high strength steels (AHSS) are typically loaded in a multiaxial stress state during forming process and service. However, the deformation mechanism under loading is not clarified, which limits optimization of sheet metal forming. In particular, due to instability, biaxial compression single thin plate has been reported, results unclear evolution yield surfaces second, third fourth quadrants σ11-σ22 space corresponding mechanisms. Therefore, AHSS plates was systematically...
The accompanying dimensional change caused by the second-order deformation behaviors severely limits accuracy of size and shape control structural parts. effect microstructure evolution mechanism on (e.g., Swift effect, inverse effect) magnesium (Mg) alloys has not been systematically reported. Therefore, in this study, order to promote precision forming Mg alloy parts, mechanisms mechanical rolled AZ31B were investigated using specifically designed multi-degree freedom multi-axial force...
The Swift effect of Mg alloy is sensitive to initial texture. However, dislocation slip the main deformation mechanism during torsion alloy. underlying relation and still not clarified. stress state pre-straining on was studied experimentally free-end for an extruded AZ31 performed with axial tension compression which lower than yield stress. It found that transition from contraction elongation occurs when changes negative positive. pre-dislocations introduced by pre-tension promote...
The variation of strain paths induces anisotropy during practical sheet forming processes, which is very important for the subsequent processing technology anisotropic Mg alloys. In this study, two-step loading tests (tension-tension) were performed to clarify effect path changes on evolution rolled AZ31 sheet. Specimens preloaded with tension along rolling direction (RD) 9% prestrain. Then, second was conducted 0°, 30°, 45°, 60° and 90° from RD. It found that yield strength increased same...
Abstract HCP metals such as magnesium are characterized by a strong interplay between dislocation slip and deformation‐induced twinning. These micromechanical processes result in complex macroscopic behavior. More precisely, addition to classical isotropic kinematic hardening, the shape of yield function changes during deformation well. This effect which is frequently referred distortional hardening particularly pronounced case non‐radial loading paths typical for most forming processes....
