The conflicts between strength and toughness
TL;DR: This work focuses on the interplay between the mechanisms that individually contribute to strength and toughness, noting that these phenomena can originate from very different lengthscales in a material's structural architecture.
Journal ArticleDOI
Strong crystal size effect on deformation twinning
TL;DR: A ‘stimulated slip’ model is developed to explain the strong size dependence of deformation twinning in crystals, and the sample size in transition is relatively large and easily accessible in experiments, making the understanding of size dependence relevant for applications.
Journal ArticleDOI
Atomistic modeling of interfaces and their impact on microstructure and properties
Yuri Mishin,Mark Asta,Ju Li +2 more
TL;DR: An overview of the most recent developments in the area of atomistic modeling with emphasis on interfaces and their impact on microstructure and properties of materials is given in this paper, along with some challenges and future research directions in this field.
Journal ArticleDOI
A review on fundamental of high entropy alloys with promising high–temperature properties
TL;DR: In this paper, the microstructures of HESAs consisting of γ and γ′ phases are similar to that of Ni-base superalloys and refractory HEAs.

Atomic, Electron and Phonon Aspects of the Edge Dislocation in Iron
H.B. Liu,J.A. Ascencio +1 more
TL;DR: In this paper, the authors summarized the recent progress of the study on edge dislocation from the point of view of atom, electron and phonon, including structure and energy of edge dislocations core, dislocation motion activated by temperature, trapping effect of dislocation on vacancy, and critical minimum size of isolated crystal grain with a stable edge dislocated, electron structure and doping effect of H, B, C, N, and O etc.
Journal Article
Formation of nanoscopic grains due to dislocation pile-up transformations in deformed ultrafine-grained materials
Ilya A. Ovid'ko,N. V. Skiba +1 more
TL;DR: In this article, a new mode of plastic deformation in ultrafine and coarse-grained polycrystalline materials is theoretically described which occurs through nanograin formation induced by stress fields and transformations of dislocation pile-ups.
Journal ArticleDOI
Fluctuation phenomena in crystal plasticity - a continuum model
Michael Zaiser,Paolo Moretti +1 more
TL;DR: In this paper, a generic continuum model is proposed to account for randomness in the local stress-strain relationships as well as for long-range internal stresses that arise from the ensuing plastic strain heterogeneities.
Journal ArticleDOI
Solute Cluster Evolution During Deformation and High Strain Hardening Capability in Naturally Aged Al-Zn-Mg Alloy
TL;DR: In this article, the effect of solute clusters on strain hardening has been systematically studied by tracing the microstructure evolution during deformation through the synchrotron X-ray diffraction and atom probe tomography techniques.

Dislocation Activity in 4H-SiC in the Brittle Domain
TL;DR: In this article, deformation experiments on 4H-SiC single crystals below the usual brittle to ductile transition temperature are reported and discussed in comparison of previous literature data, showing that dislocation activity under high stress is more complex than expected.
