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

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.

Some Aspects of Coherent Epitaxial Deposits

TL;DR: In this article, the authors show that coherent epitaxies on a planar substrate build up continuous pseudomorphous layers A which are fully strained according to their natural misfit m. The so-accumulated strain energy density is responsible for some remarkable facts: 1) each layer is formed at precise undersaturation.
Journal ArticleDOI

Effect of Eshelby twist on core structure of screw dislocations in molybdenum: atomic structure and electron microscope image simulations

TL;DR: In this paper, the core structure of screw dislocations in elastically anisotropic Mo in the bulk can be obtained from high-resolution electron microscopy (HREM) images viewed end-on in a thin foil.
Journal ArticleDOI

A study of the accommodation of coherency strain by interfacial defects at a grain boundary in gold

TL;DR: In this paper, the structure of a ⟨ 110 ⟩ 90° grain boundary in Au is investigated using high-resolution transmission electron microscopy (HRTEM) and atomistic simulation.
Journal ArticleDOI

Kinetic Monte Carlo approach to modeling dislocation mobility

TL;DR: In this paper, a kinetic Monte Carlo (kMC) approach is used to model the kink nucleation and migration of screw dislocation in BCC metals, and the authors find that the accuracy of the model predictions cannot claim to be quantitative because of uncertainties in the atomistic results for kink energetics.
Journal ArticleDOI

Stable Defects in Semiconductor Nanowires.

TL;DR: Study of individual nanowires using cathodoluminescence show that optical emission is quenched in defective regions, showing that they act as strong nonradiative recombination centers.
