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.

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-scale study of dislocation glide in a model solid solution
TL;DR: In this paper, the dislocation pinning mechanism in a dilute Ni(Al) model solid solution was studied and a method to address thermal activation was proposed and exemplified on a periodic row of solute pairs.
Journal ArticleDOI
Collective nature of plasticity in mediating phase transformation under shock compression
Hongxiang Zong,Hongxiang Zong,Xiangdong Ding,Turab Lookman,Ju Li,Ju Li,Jun Sun,Ellen K. Cerreta,Juan P. Escobedo,Francis L. Addessio,Curt A. Bronkhorst +10 more
TL;DR: In this paper, the authors show that a deformation mode not present in static conditions plays a dominant role in mediating plastic behavior in hcp metals and determines the course of the transformation.
Journal ArticleDOI
Modelling size effects using 3D density-based dislocation dynamics
TL;DR: In this article, density-based continuity equations are used to model strain patterns and size effects in confined plastic flow, namely, shearing of thin films and microbending, and a representation in terms of coupled equations for the densities of screw and edge components.
Journal ArticleDOI
Solute cluster evolution during deformation and high strain hardening capability in naturally aged Al–Zn–Mg alloy
TL;DR: In this paper, the effect of solute clusters on strain hardening has been investigated by tracing the microstructure evolution during deformation through synchrotron X-ray diffraction and atom probe tomography, and the experimental evidence strongly suggest that dislocation multiplication dominates over the entire deformation process until failure in NA alloys.

Interaction of a moving { } twin boundary with perfect dislocations and loops in a hcp metal
Anna Serra,David Bacon +1 more
TL;DR: In this article, an atomic-scale computer simulation is used to investigate the interaction of a moving twin boundary in a hcp metal with either a straight 1/3 dislocation lying perpendicular to the direction of twinning shear or a periodic row of perfect dislocation loops.
