Field dislocation mechanics and phase field crystal models
Amit Acharya,Jorge Viñals +1 more
TL;DR: In this paper, a phase field crystal model is presented that is consistent with the necessary microscopic independence between the phase field, reflecting the broken symmetry of the phase, and both mass density and elastic distortion.
Journal ArticleDOI
Misfit Dislocation Patterning in Thin Films
TL;DR: In this paper, a three-element reaction-diffusion model for the kinetics of gliding, climbing and misfit dislocations is used to describe the corresponding pattern, and analytical solutions of the model are obtained which describe transient spatially uniform dislocation distributions, as well as steady-state spatially periodic dislocations distributions.
Journal ArticleDOI
Atomic-resolution imaging of lattice imperfections in semiconductors by combined aberration-corrected HRTEM and exit-plane wavefunction retrieval
TL;DR: In this article, the benefits of a combination of spherical aberration-corrected imaging and numerical retrieval of the exit-plane wavefunction from a focal series of micrographs are illustrated by highlighting their combined use for atomic-scale characterization of lattice defects frequently observed in common semiconductor materials.
Journal ArticleDOI
Molecular Mechanisms of Superelasticity and Ferroelasticity in Organic Semiconductor Crystals
TL;DR: In this article, the cooperative phase transition is used to enable flexible organic crystals enabled by cooperative phase transitions. But, it is not suitable for solid-state chemistry to produce light, biocompatible, and environmentally benign devices.
Journal ArticleDOI
Comparison of Ni-based alloys with extreme values of antiphase boundary energies: dislocation mechanisms and mechanical properties
TL;DR: In this article, the yield-stress anomaly in L12 nickel-based alloys with high (Ni74Al26), medium (Ni3(Al, 0.25%Hf)), and low (Ni 3Ga) antiphase boundary (APB) energies was measured and compared with those found in the literature.

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.

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...
