Entwicklung einer versetzungsbasierten Kontinuumstheorie mittels mechanismusbasierter Homogenisierung
TL;DR: In this article, a mechanismusbasierte homogenisierung der Wechselwirkung von Versetzungen eines Gleitsystems in 2D and eine Homogenisiersierung des Frank-Read-Mechanismus zur Produktion of Versetungsdichte hergeleitet is discussed.

Transmission electron microscopy study of heterostructures grown on GaAs (110)
TL;DR: In this paper, the microstructural properties of (110)-oriented heterostructures on GaAs substrates were systematically investigated by means of different transmission electron microscopy techniques, and defect-free structures were successfully acquired by an appropriate type of AlAs/GaAs/Uberstruktur.
Journal ArticleDOI
Vibrational properties of grain boundaries in nanocrystalline Ni using second moment potentials
TL;DR: The high frequency phonon properties of a computer-generated nanocrystalline (nc) Ni are investigated by directly calculating the onsite phonon Green function using a recursion technique based on a continued fraction representation as discussed by the authors.
Journal ArticleDOI
A Method to Distinguish Twinning Variants and Second Twins by EBSD Measurements
TL;DR: In this paper, a direct and simple method to identify the second twins from twinning variants by electron back scattered diffraction (EBSD) was proposed to clarify the orientation relationship between the neighboring crystals, the misorientation calculation by MATLAB software based on the EBSD data was also used.

Correlation between plasticity and dislocation dissociation in ceramics
Miguel Castillo-Rodríguez,Ángela Gallardo-López,Antonio Muñoz,Jacques Castaing,Arturo Domínguez-Rodríguez +4 more
TL;DR: The influence of dislocation core extension on plastic properties is discussed in this paper, where the authors discuss the reasons for such effects, emphasising factors that can reduce the mobility of dislocations to justify why dissociation can influence plasticity and has negligible effects.

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.

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.
