Advanced Functional Materials, EarlyView.In the work reported herein, dipole‐engineered sulfonated carbon nanofibers enable conductive additives to actively regulate interphase formation in silicon anodes. Polar sulfonyl groups guide electrolyte decomposition to form a compact LiF‐rich interphase while promoting robust integration with silicon.

LAOS: The strain softening/strain hardening paradox
Journal of Rheology, 2014 Numerous materials, from biopolymers to filled rubbers, exhibit strain softening at high strain amplitudes during a strain sweep in oscillatory rheology: The modulus decreases with increasing deformation. On the other hand, if the nonlinear elastic response is analyzed within a single oscillation cycle (described by a Lissajous curve), these systems ...

Strain hardening of rail steel
Deformation and Fracture of Materials, 2023Based on the results of studying the evolution of structural-phase states and the dislocation substructure of rail steel under uniaxial compression deformation up to a degree of 50%, a quantitative analysis of the hardening mechanisms of this steel under compression conditions has been performed.

On the Characterization of Strain-Hardening in Plasticity
Journal of Applied Mechanics, 1981In the context of a purely mechanical, rate-type theory of elastic-plastic materials and utilizing a strain space formulation introduced in [1], this paper is concerned mainly with developments pertaining to strain-hardening behavior consisting of three distinct types of material response, namely, hardening, softening, and perfectly plastic behavior ...

Hardening the surface of austenitic steels by strain hardening
Metal Science and Heat Treatment, 19711. The carrying capacity in terms of permissible stress (σ0, 2) of steels Kh18N10T and Kh21N5AG7 under conditions of uniaxial static tension increases 50% down to −253° as the result of surface hardening. 2. For hardened steels Kh18N10T and Kh21N5AG7 σ b n /σn > 1 and σ b n /σ0.2 > 1 with Kt=3.0 in the range of 20 to −253° C. 3.

Strain hardening of aluminium at high strains
Acta Metallurgica, 1983Abstract The paper brings a critical analysis of the shape of the strain hardening curve of aluminium within the range of high strains. Basing on a statistical analysis it has been shown that the hardening curve has a series of plateaus. The structural investigations indicate that the plateaus on the hardening curve correspond to heterogeneous ...

Tensile instability and necking in materials with strain hardening and strain-rate hardening
Acta Metallurgica, 1977Abstract An in-depth examination of tensile instability and necking in materials with strain hardening and strain-rate hardening has been made to clear up some recent controversies on this subject. A simplified analytical model presented here reveals that a preexisting geometric imperfection can grow from the outset of deformation (i.e.

FRACTOGRAPHIC studies1–3 using optical and electron microscopy have shown that, for many metals, high-strain fatigue endurance is determined by crack propagation of the type designated stage II by Forsyth4. This is contrary to the statistical argument put forward by Gittus5 and the dislocation intersection model of Gilman6, neither of which is in ...
