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.

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.

Heterogeneous precipitation on dislocations: effect of the elastic field on precipitate morphology
TL;DR: In this paper, the shape of a coherent non-misfitting FeC precipitate formed from solute atoms that interact with a dislocation stress field was studied using kinetic Monte Carlo simulation on a rigid lattice.
Dissecting the Mechanism of Martensitic Transformation via Atomic-Scale
TL;DR: In this article, high-resolution transmission electron microscopy (HRTEM) observations confirm the crucial role of partial dislocations, and reveal tell-tale features including the lattice rotation of thea9 martensite inclusion, the transition lattices at the e/a9 interfaces that cater the shears, and the excess reverse shear-shuffling induced c necks in the e martENSite plates.
Journal ArticleDOI
Residual Stress Removal Under Pulsed Electric Current
Siqi Xiang,Xinfang Zhang +1 more
TL;DR: In this article, the effect of a pulsed electric current on the residual stress evolution of metal materials has been investigated, and it was found that the surface and internal residual stresses in the as-quenched samples were reduced dramatically by electropulsing.
Journal Article
Distributed-activation kinetics of heterogeneous martensitic nucleation
TL;DR: Lin et al. as discussed by the authors showed that the potency distribution of preexisting and autocatalytically generated defects obeys a Gaussian function, whereas that of the auto-catalytic defects obey an exponential function.

Microstructure–strength models for heat treatment of Al–Si–Mg casting alloys I: microstructure evolution and precipitation kinetics
TL;DR: In this article, a comprehensive microstructure-strength mathematical model for the heat treatment of Al-Si-Mg casting alloys is presented, and the evolution of micro-structure and mechanical properties during heat treatment is studied in an extensive experimental investigation.
