Computer Simulation of the Interaction of Junction Disclinations in Nanomaterials with Grain Boundary Vacancies
Ayrat A. Nazarov,R. T. Murzaev +1 more
TL;DR: In this article, the effect of junction defects on the formation energy of vacancies in grain boundaries (GBs) is studied by means of atomistic computer simulations, and it is shown that at least two orders of magnitude increase of the GB diffusion coefficient can be expected due to junction disclinations in nanostructured metals.

In-situ TEM Study of Dislocation-Interface Interactions
TL;DR: In this article, the in situ transmission electron microscope (TEM) observation of the interactions of dislocations with three types of interfaces: (i) twin boundaries in Cu; (ii) metallic interphase boundaries; and (iii) metal/ceramic interfaces.
Ferroelectric Switching and d33 Mapping of Micro-Patterned Piezoelectrics by Piezo Force Microscopy
TL;DR: Ye et al. as mentioned in this paper used PFM to track the domain orientations and switching dynamics of PZT and PMN-PT thin-film structures for geometrically strain-relieved samples.

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.
