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.

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.

Modeling of Dislocation Interaction with Solutes, Nano-Precipitates and Interfaces: A Multiscale Challenge
TL;DR: In this article, a review of multiscale methods that have been developed to determine dislocation properties and interactions in metals is presented, which includes: (1) dislocation core properties in fcc and bcc metals; (2) the effect of solutes or nanoprecipitates on the mobility of a screw dislocation in bcc metal; (3) the interaction between dislocations and precipitates in intermetallic compounds; and (4) the transmission of dislocation through coherent and incoherent interfaces.
Journal ArticleDOI
Atomic processes of shear-coupled migration in { 112 } twins and vicinal grain boundaries in bcc-Fe
TL;DR: In this article, the authors characterize the source of dislocations in bcc metals and describe the mechanism that allows the source to move conservatively with the grain boundary during grain boundary migration.
Journal ArticleDOI
Instabilities of High Speed Dislocations.
TL;DR: It is shown that the existence of mechanical instabilities in the system are found at material-dependent velocities far below the speed of sound, which are the onset of an atomistic kinematic generation mechanism, which ultimately results in an avalanche of further dislocations.

Atomistic simulations of the tensile strength of a disclinated bicrystalline nanofilm
Kun Zhou,A.A. Nazarov,Mao S. Wu +2 more
TL;DR: The tensile strength of a bicrystalline nanofilm containing a wedge disclination in the middle of a grain boundary (GB) terminating at the film surfaces was studied via atomistic simulations as mentioned in this paper.

A look-up table based approach to characterize crystal twinning for synchrotron X-ray Laue microdiffraction scans.
Yao Li,Liang Wan,Kai Chen +2 more
TL;DR: An automated method has been developed to characterize the type and spatial distribution of twinning in crystal orientation maps from synchrotron X-ray Laue microdiffraction results.
