Thermodynamic dislocation theory: Bauschinger effect [PDF]
Physical Review E, 2018 The thermodynamic dislocation theory developed for non-uniform plastic deformations is used here to simulate the stress-strain curves for crystals subjected to anti-plane shear-controlled load reversal. We show that the presence of the positive back stress during the load reversal reduces the magnitude of shear stress required to pull excess ...

In Situ TEM Observation of Cooperative Grain Rotations and the Bauschinger Effect in Nanocrystalline Palladium [PDF]
Nanomaterials, 2021 We report on cooperative grain rotation accompanied by a strong Bauschinger effect in nanocrystalline (nc) palladium thin film. A thin film of nc Pd was subjected to cyclic loading–unloading using in situ TEM nanomechanics, and the evolving ...

The Bauschinger effect in stainless steel orthodontic wires
Australasian Orthodontic Journal, 1987 The existence and clinical importance of the Bauschinger effect has received little attention in the orthodontic literature. Essentially, the Bauschinger effect describes the reduction in yield stress of a metal when the direction of defamation is ...

The Bauschinger Effect Magnitude Control in Ultra-Low Carbon Steel Wires [PDF]
Materials Research, 2023 The cold roller die process increases the tensile strength and decreases the ductility of steel wire. Annealing heat treatment is applied to restore mechanical properties, but this is a costly process.

Structure Refinement and Bauschinger Effect in fcc and hcp Metals
Metals, 2023 Although the Bauschinger effect has been investigated in some detail in various materials, the number of articles on the effect of grain size is extremely limited, and in current nanostructured materials it is practically absent. Since such materials are

Journal of Materials Research and Technology, 2022 The failure modes and mechanisms of single and polycrystalline aluminum under different stress states are very different. Therefore, molecular dynamics methods were used to study the tension-compression asymmetry and Bauschinger effect of single and ...

Low cycle fatigue properties of extruded magnesium AZ31B [PDF]
FME Transactions, 2022 The low cycle fatigue behavior of magnesium (Mg) AZ31B was observed at room temperature, in which its extrusion process led to differences in tensile and compressive stresses, with an increase in the grain structure and mechanical properties.

Influence of near-surface dislocation cellular structure on Bauschinger effect
Journal of Materials Research and Technology, 2021 Long range internal stress (LRIS) based mechanism and non-LRIS explanation regarding Bauschinger effect are in debate. LRIS is originated from dislocation pile-up and/or cell generated by the pre-loading, therefore dislocation structure characterization ...
