On the disclination-structural unit model of grain boundaries
The relation between two elastic continuum approaches to grain boundary structure, the dislocation and disclination models, is discussed. It is shown that the disclination model has two advantages: a well-behaved expression for the elastic energy of disclination dipole walls, which describes the elastic energy over a wide interval of misorientations, and a continuous misorientation angle depend...
متن کاملBasic Structure of Infrared Glasses
A phenomenological theory, designiued herein as the unified glass theor;', is presented. The theory introduces the concept of order-disorder transitions and liquid-model transformation within a gla^s network and was found to be useful in elucidating and predicting structural behavior. The degree of order and the structural characteristics of a glass system were represented by three existing mod...
متن کاملGlass-Like Heat Conduction in Materials With Disclination-Induced Topological Disorder
The recent progress in a study of various topologically disordered materials shows clearly an importance of rotational defects: disclinations, disclination dipoles, and disclination loops. Surprisingly, the phonon scattering due to strain fields caused by biaxial wedge disclination dipoles (BWDDs) turned out to be rather unusual (the mean free path lD ∼ q−1 at small q while lD → const with q in...
متن کاملAtomic-level observation of disclination dipoles in mechanically milled, nanocrystalline Fe.
Plastic deformation of materials occurs by the motion of defects known as dislocations and disclinations. High-resolution transmission electron microscopy was used to directly reveal the individual dislocations that constitute partial disclination dipoles in nanocrystalline, body-centered cubic iron that had undergone severe plastic deformation by mechanical milling. The mechanisms by which the...
