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.

Transformation behaviour and unusual twinning in a NiTi shape memory alloy ausformed using equal channel angular extrusion
TL;DR: In this article, the effect of severe plastic deformation on the interplay between dislocation slip and twinning and forward and reverse martensitic transformation was investigated. But the results were limited to the case of Ti-50.8% Alloy.
Journal ArticleDOI
Nanovoid cavitation by dislocation emission in aluminum.
TL;DR: This Letter is concerned with the determination of the transition paths attendant to nanovoid growth in aluminum under hydrostatic tension, and reveals several stages of pressure buildup separated by yield points.
Journal ArticleDOI
Mechanism and energetics of 〈c + a〉 dislocation cross-slip in hcp metals.
TL;DR: At atomistic simulations in Mg reveal the unusual mechanism of 〈c+a〉 dislocation cross-slip between pyramidal I and II planes, which occurs by cross-Slip of the individual partial dislocations.
Journal ArticleDOI
Avalanches and Scaling in Plastic Deformation
TL;DR: This model of dislocation loops using an analytically solvable phase-field model of dislocations for ductile single crystals during monotonic loading predicts a range of macroscopic behaviors in agreement with observation, including hardening with monotony loading, and a maximum in the acoustic emission signal at the onset of yielding.
Journal ArticleDOI
Spiral Patterns of Dislocations at Nodes in (111) Semi-coherent FCC Interfaces
TL;DR: Combining atomistic simulation and dislocation theory, these features are proven universal corresponding to the node density and the character of interface dislocations.
