Investigation of High-Temperature Constitutive Behavior of Ti555211 Titanium Alloy Subjected to Plastic Deformation in the Different Phase Regions

Metals, 2022
Ti555211 titanium alloy is subjected to plastic deformation in the dual-phase (α + β phase) zone and single-phase (β phase) zone at various deformation temperatures and strain rates.

Plastic deformation of metallic glasses: Size of shear transformation zones from molecular dynamics simulations [PDF]

, 2006
Plastic deformation in metallic glasses well below their glass transition temperatures Tg occurs spatially heterogeneously within highly localized regions, termed shear transformation zones (STZs).

Predicting the onset of rafting of c 0 precipitates by channel deformation in a Ni superalloy [PDF]

, 2010
The growth or shrinkage, normal to 001, of the interfaces between the γ matrix and cuboidal γ' precipitates is examined for a Ni-base superalloy, by considering the force acting on the interfaces. The force is produced by the precipitate coherency misfit

Large deformation plasticity

Acta Mechanica Sinica, 2020
AbstractThe theory of plasticity as a special field of continuum mechanics deals with the irreversible, i.e. permanent, deformation of solids. Under the action of given loads or deformations, the state of the stresses and strains or the strain rates in these bodies is described.

Plastic Deformation of Protein Monolayers [PDF]

Biophysical Journal, 2002
Globular proteins are peculiar solids that display both local stability of their conformation and the ability to undergo large cooperative changes of shape (conformational changes). If one forces a large deformation of the molecule, such that the structure is necessarily changed, it is not obvious whether the deformed globule can still remain a solid ...

Synergetics of Plastic Deformation

Успехи физики металлов, 2001
The process of the developed plastic deformation is studied when defects density is so high that collective effects play key role. On the basis of conception of rearrangable potential relief, the field theory of the superplastic-state type of the Lüders ...

Micro-scale strain distribution in hot-worked duplex stainless steel [PDF]

, 2005
A modified microgrid technique has been applied to a laboratory-made duplex stainless steel, to experimentally simulate the local state of deformation of the austenite-ferrite microstructure of low-alloy steels subject to intercritical deformation.
