Journal ArticleDOI
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.

Stacking fault emission from grain boundaries: Material dependencies and grain size effects
TL;DR: In this paper, the effect of applied stress, 3D grain size, material stacking fault energies, and grain boundary ledge size on the stress-driven emission of leading and trailing partial dislocations from a grain boundary is investigated.
Journal ArticleDOI
Modeling of Dislocation Structures in Materials
Jeffrey M. Rickman,Jorge Viñals +1 more
TL;DR: In this paper, a phenomenological model of the evolution of an ensemble of interacting dislocations in an isotropic elastic medium is formulated, and the line-defect microstructure is described in terms of a spatially coarse-grained order parameter, the dislocation density tensor.
Journal ArticleDOI
Interactions of Moving Dislocations in Semiconductors with Point, Line and Planar Defects
TL;DR: In this article, the authors demonstrate that strained GeSi/Si heterostructures act as a model system for the study of the interaction of propagating dislocations with point, line and planar defects.
Journal ArticleDOI
First-principles density functional theory study of generalized stacking faults in TiN and MgO
TL;DR: In this article, the generalized stacking fault (GSF) energies in different slip planes of TiN and MgO are calculated using highly reliable first-principles density functional theory (DFT) calculations.
Journal ArticleDOI
Continuum theory of evolving dislocation fields
TL;DR: In this article, the concept of single-valued dislocation fields that enable us to keep track of the curvature of the continuously distributed gliding dislocations with line tension is utilized.
