Dislocations in amorphous materials
2014 The general aim of this paper is to provide a better understanding of amorphous materials, with special reference to glassy and granular systems, indicating areas where the behaviour of these two may be similar. We lay special emphasis on granular systems, as befits their importance as a newly emerging field of study in physics, and present a review of recent progress in understanding thei...

متن کاملDomain Wall Pinning in Inhomogeneously Deformed Amorphous Alloys
Inhomogeneous deformation in amorphous alloys is characterized by local regions of intense shear. Experiments on VITROVAC 0040 (Fe40Ni40B20) supplied by Vacuumschmelze (Hanau, Germany) show a direct correlation between the number density of the shear bands and the coercive field after inhomogeneous deformation by cold rolling. The deformation process is also shown to induce an off axis magnetic...
متن کاملReversible plastic events in amorphous materials.
For crystalline materials, the microscopic origin of plasticity is well understood in terms of the dynamics of topological defects. For amorphous materials, the underlying structural disorder prevents such a description. Therefore identifying and characterizing the microscopic plastic events in amorphous materials remains an important challenge. We show direct evidence for the coexistence of re...
متن کاملThermal transport in amorphous materials: a review
Thermal transport plays a crucial role in performance and reliability of semiconductor electronic devices, where heat is mainly carried by phonons. Phonon transport in crystalline semiconductor materials, such as Si, Ge, GaAs, GaN, etc, has been extensively studied over the past two decades. In fact, study of phonon physics in crystalline semiconductor materials in both bulk and nanostructure f...
