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.
Journal ArticleDOI

Lattice wave emission from moving cracks
TL;DR: In this article, a simple modification of the interatomic potential switches the crystal behavior from brittle to ductile, substituting dislocations to daughter cracks, and the steady state velocities are the same, whether the model crystal is brittle or ductile.
Journal ArticleDOI
Micromechanics of defects in transversely isotropic elastic solids with interfaces
TL;DR: In this article, a modified point force method is proposed to obtain the explicit three-dimensional closed form elastic solution in solids with defects in the presence of an interface, where the solids are either perfectly bonded together or in frictionless contact with each other at the planar interface.
Journal ArticleDOI
Mechanism of Stress-Driven Grain Boundary Migration in Nanotwinned Materials
TL;DR: In this paper, a stress-driven grain boundary migration in ultrafine-grained materials with nanotwinned structure is theoretically described and the energy and critical stresses of the GB migration accompanied by the twin boundary migration are calculated.
Journal ArticleDOI
Long-term natural ageing of a dissociated dislocation in a Cu-13.43 at.% Al alloy
TL;DR: It is concluded that the Suzuki effect is responsible for the widening of dislocations introduced by plastic deformation in a Cu-13.43 at.% Al alloy 38 years ago.
Journal ArticleDOI
The Topological Model (TM) of Martensite Transformations - Some Improvements.
Patrick M. Kelly,Dong Qiu +1 more
TL;DR: In this paper, a modified version of the Frank-Bilby equation for the TM equation was used to calculate the shape strain, its magnitude and direction, and a simpler and more accurate expression for the tilt rotation was also presented.
