Abstract: In the current work, the strain hardening behavior of dual-phase steels with different silicon content (0.34- 2.26 Wt. %) was examined using the modified Crussard-Jaoul analysis. It was shown that these dual-phase steels deform in two stages over a uniform strain range. Each stage exhibited a different strain hardening exponent varying with silicon content. At the first stage, work...

2 national X ray digital imaging center; Mianyang,China Abstract Beam Hardening effect would be induced due to broad energy spectrum of X-ray. Beam Hardening would lead to artifacts in CT reconstructed images, such as cupping artifact, streak artifact and metal artifact, so that the quality of CT image degrades. One efficient beam hardening correction method is building a mathematical law betwe...

Recent failures of production systems have highlighted the importance of tolerating faults beyond crashes. The industry has so far addressed this problem by hardening crash-tolerant systems with ad hoc error detection checks, potentially overlooking critical fault scenarios. We propose a generic and principled hardening technique for Arbitrary State Corruption (ASC) faults, which specifically m...

Rapid wilting of cabbage leaves (Brassica capitata L.), induced by excision of the shoot, induced as rapid and high a degree of freezing resistance as a similar period of hardening at low temperature. Maximum hardening in the leaf was generally associated with the maximum growth rate. On the other hand, exposure of the excised shoot to low temperature while immersed in aerated water failed to h...

The mechanical behavior of a single phase (fcc) Al0.3CoCrFeNi high-entropy alloy (HEA) was studied in the low and high strain-rate regimes. The combination of multiple strengthening mechanisms such as solid solution hardening, forest dislocation hardening, as well as mechanical twinning leads to a high work hardening rate, which is significantly larger than that for Al and is retained in the dy...

The age hardening of an Al-Mg-Si alloy was enhanced by the effect of high-speed (105 s11) compression prior to aging. This enhancement of the age hardening is brought about by the formation of vacancy clusters during high-speed compression. High resolution transmission electron microscopy reveals that these vacancy clusters form stacking fault tetrahedra. Following peak aging, vacancy clusters ...

The data presented in this article are related to the research article entitled "On the plasticity mechanisms of lath martensitic steel" (Jo et al., 2017) [1]. The strain hardening behavior during tensile deformation of a lath martensitic press hardening steel was described using a dislocation density-based constitutive model. The Kubin-Estrin model was used to describe strain hardening of the ...

The changes in the mechanical properties and microstructure of nanocrystalline Cu-Zn alloys deformed by cryorolling during low temperature annealing and the post-process deformation were studied. The deformed Cu-Zn alloys exhibited uncommon anneal hardening and deformation softening behaviors. The degree of anneal hardening and deformation softening increased with the addition of the solute ato...

During the first stage of hardening of winter rape plants (Brassica napus L. var. oleifera L., cv. Górczański), marked increase of ATP content in leaves was observed. Lowering the temperature from 5 to 0 C (the second stage of hardening) had no further effect on ATP content. In roots, not capable of hardening, pronounced decrease of ATP content was noted after prolonged exposure to cold. It was...

It is well known that size effects are present in plasticity with the observation that smaller being the stronger. This effect is attributed to the presence of geometrically necessary dislocations (GNDs). The hardening associated to GNDs can be separated in two groups: energetic and dissipative. The fi rst is associated with defect energy and different defi nitions for it are possible. In all c...
