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.

Non-singular descriptions of dislocation cores: a hybrid ab initio continuum approach
TL;DR: In this article, a hybrid approach that links the parametric dislocation dynamics method with ab initio calculations is presented, which is an extension of the Peierls-Nabarro (PN) model, with the following features: (1) all three components of the displacement vector for atoms within the dislocation core are included; (2) the entire generalized stacking fault energy surface (GSFS) obtained from ab-initio calculations; and (3) the method is generalized to treat curved dislocations.
Journal ArticleDOI
Numerical investigation of the interaction between the martensitic transformation front and the plastic strain in austenite
TL;DR: In this paper, phase-field simulations of the martensitic transformation with plastic deformation are carried out, where the elasto-plastic phase field approach of semicoherent MT is used.
Journal ArticleDOI
Ultrasound as a probe of plasticity? the interaction of elastic waves with dislocations
TL;DR: These results explain a number of recent, hitherto unexplained, experimental findings on the interaction of elastic waves with dislocations.
Journal ArticleDOI
Note on wavefront dislocation in surface water waves
Natanael Karjanto,E. van Groesen +1 more
TL;DR: In this article, it is shown that the Chu-mei quotient is necessary and sufficient for phase singularity and wavefront dislocation at singular points of a wave field.

Lattice resistance to dislocation motion at the nanoscale.
TL;DR: A model is proposed that demonstrates the effect of a free surface on the lattice resistance experienced by a moving dislocation in nanodimensional systems, which manifests in an enhanced velocity of dislocation due to the proximity of the dislocation line to the surface.
