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.

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.

Dislocation-based continuum models of crystal plasticity on the micron scale
TL;DR: In this paper, the authors investigated the ubiquitous size effects in plastic deformation of micron-scale specimens and investigated the relationship between internal and external length scales in a system where dislocations, in the form of continuous lines embedded in a threedimensional isotropic medium, move, expand, interact, and thus create plastic distortion on the deforming body.

A New Insight in the Plasticity of Ni3Al Intermetallic Compounds Using AFM Observations
TL;DR: In this article, the positive temperature dependence of flow stress in Ni3Al was examined through fine slip trace analysis performed by atomic force microscopy, showing that the anomaly domain is accompanied by a drastic exhaustion of mobile dislocations and very short cross-slip distances on the cube crossslip plane.
Journal ArticleDOI
Contribution of AFM Observations to the Understanding of Ni 3 Al Yield Stress Anomaly
TL;DR: In this paper, the use of atomic force microscopy allowed an irrefutable insight in material plasticity for discriminating between different modelling hypotheses concerning the yield stress anomaly of Ni3Al intermetallic compounds with the L12 ordered structure.

Modeling of Grain Subdivision during Severe Plastic Deformation by VPSC Method Combined with Disclination Analysis
A. A. Nazarov,A. A. Nazarov,Nariman A. Enikeev,A. E. Romanov,T. S. Orlova,Igor V. Alexandrov,Irene J. Beyerlein +6 more
TL;DR: In this paper, the viscoplastic self consistent (VPSC) method and a disclination model were used to model the deformation of a simple shear grain. But the results showed that the texture was not insensitive to the presence of subgrains with misorientations less than 15°.
