Journal ArticleDOI
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.
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.
Journal ArticleDOI
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.
Journal ArticleDOI
The Peierls stress in a simple cubic lattice
TL;DR: In this paper, the Peierls model is used to describe the behavior of a straight dislocation in a crystal lattice. But the authors assume that the dislocations are aligned along close-packed directions in a lattice and that the maximum energy variation is defined by the maximum gradient of the misfit energy EA.

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.
Journal ArticleDOI
Heterostructured materials: superior properties from hetero-zone interaction
Yuntian Zhu,Kei Ameyama,Peter M. Anderson,Irene J. Beyerlein,Huajian Gao,Hyoung Seop Kim,Enrique J. Lavernia,Suveen N. Mathaudhu,Haël Mughrabi,Robert O. Ritchie,Nobuhiro Tsuji,Xiangyi Zhang,Xiaolei Wu +12 more
Abstract: Heterostructured materials are an emerging class of materials with superior performances that are unattainable by their conventional homogeneous counterparts. They consist of heterogeneous zones wi...
