Analysis of Strain Hardening Stages of AISI 316 LN Stainless Steel Under Cold Rolling Conditions

Metals
In the present investigation, stress–strain curves and strain hardening rates on samples rolled at ambient temperature with thickness reductions of 0%, 10%, 30%, and 50% were studied.

Tensile Strain Hardening Behavior and Fractography of Superalloy GH39

Journal of Aeronautical Materials, 2016
The strain hardening behaviour and fractography of superalloy GH39 was investigated by tensile test at different strain rates. Results indicate that strain hardening behaviours are different during the deformation process.

Strain hardening behaviors and strain rate sensitivity of gradient-grained Fe under compression over a wide range of strain rates

, 2016
In the present work, gradient-grained Fe was synthesized by means of surface mechanical grinding treatment, and then the compression behaviors of the coarse-grained Fe and the gradient-grained Fe were investigated under both quasi-static and dynamic ...

Modelling, identification and application of phenomenological constitutive laws over a large strain rate and temperature range [PDF]

, 2013
A review of the different phenomenological thermo-viscoplastic constitutive models often applied to forging and machining processes is presented. Several of the most common models have been identified using a large experimental database (Hor et al., 2013)

Tensile strain-hardening behavior and related deformation mechanisms of pure titanium at cryogenic temperature

Journal of Materials Research and Technology, 2023
The tensile strain-hardening behavior of pure Ti at 100 K was investigated using X-ray diffraction line-profile analysis and plasticity simulation. The strain hardening was significantly increased at 100 K, compared with that observed at 298 K.

Plasticity size effects in tension and compression of single crystals [PDF]

, 2005
The effect of size and loading conditions on the tension and compression stress–strain response of micron-sized planar crystals is investigated using discrete dislocation plasticity.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Contribution of Different Hardening Mechanisms during Cold Working of AISI 304L Austenitic Stainless Steel [PDF]

Archives of Metallurgy and Materials, 2018
The contributions of work-hardening of austenite and the presence of martensite on the hardening of an AISI 304L stainless steel were evaluated based on plastic deformation under different reductions in thickness at two rolling temperatures.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Computational modeling of dynamic mechanical properties of pure polycrystalline magnesium under high loading strain rates

EPJ Web of Conferences, 2015
Computational simulations were performed to investigate the dynamic mechanical behavior of pure polycrystalline magnesium under different high loading strain rates with the values of 800, 1000, 2000, and 3600 s−1.
