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.

Thermodynamic theory of dislocation-enabled plasticity
TL;DR: This paper consists of a systematic reformulation of this theory followed by examples of its use in analyses of experimentally observed phenomena including strain hardening, grain-size (Hall-Petch) effects, yielding transitions, and adiabatic shear banding.
Journal ArticleDOI
Influence of heterointerface atomic structure and defects on second-harmonic generation
TL;DR: Newly developed photomodulation-second-harmonic-generation experiments reveal that the interfacial region contains predominantly hole traps, and that the density of these traps is substantially lower for 3\ifmmode\times\else\texttimes\fi{}1 buried surface reconstructed samples.
Journal ArticleDOI
General framework for acoustic emission during plastic deformation
TL;DR: In this paper, a discrete wave equation with plastic strain rate as a source term and include the Rayleigh-dissipation function to represent dissipation accompanying acoustic emission is devised for bridging the widely separated time scales of plastic deformation and elastic degrees of freedom.
Journal ArticleDOI
Disconnections in simple and complex structures
TL;DR: In this article, the authors analyzed disconnection mobility in terms of shear and shuffle-type atomic displacements and diffusional flux in a sequence of hetero-phase materials with increasing structural complexity.

John C. H. Spence,H. R. Kolar,Gary G. Hembree,Colin J. Humphreys,Jonathan S. Barnard,Ranjan Datta,Christoph Koch,Frances M. Ross,João F. Justo +8 more
TL;DR: In this paper, forbidden reflection lattice images recorded in an ultra-high vacuum TEM in projections normal to the dislocation line could provide interpretable images of cores at atomic resolution.
