Amorphization by Solid-State Reaction
Solid State Phenomena, 1990New processes for preparing amorphous alloys have been recently developed. In contrast with conventional methods based on liquid quenching, the starting materials are in a crystalline state and the amorphization takes place in the solid state. The processes reviewed here include solid-gas reactions, amorphization of multilayers, mechanical alloying of ...

Surface Crystallization of Amorphous Solid Water
Physical Review Letters, 2004We demonstrate that the crystallization of thin, supported amorphous solid water layers is initiated at the water surface. This is concluded from the observation of sequential crystallization of amorphous water at the surface, in the bulk, and at the water-support interface.

Crystalline and Amorphous Solids
2020When discussing crystalline and amorphous, a reference in the crystal structure is made. Crystalline refers to the orderly structure of the atoms, while the amorphous crystals are disorderly. This difference refers to the difference in the terms, but if a metal is crystalline in structure and another metal is amorphous in structure how does this ...

Eshelby problem in amorphous solids
Physical Review EThe Eshelby problem refers to the response of a two-dimensional elastic sheet to cutting away a circle, deforming it into an ellipse, and pushing it back. The resulting response is dominated by the so-called Eshelby kernel, which was derived for purely elastic (infinite) material, but has been employed extensively to model the redistribution of stress ...

Journal of Non-Crystalline Solids, 1985
Abstract The three classical models of amorphous solids are: the continuous random network model for covalent glasses (Zachariasen), the random close packing model for metallic glasses (Bernal), and the random coil model for polymeric glasses (Flory).

Ferromagnetism in amorphous solids
AIP Conference Proceedings, 1975Experimental results on ferromagnetism in amorphous metals and alloys are reviewed, together with models for atomic arrangements in these materials. Consequences of chemical and structural disorder are discussed, with particular emphasis on magnetic moments, spin waves, and the temperature dependence of magnetization in amorphous ferromagnets.

Cryogenics, 1988
Abstract At low temperatures amorphous solids exhibit a variety of unusual properties. Thus far these anomalies can be described only on the basis of a phenomenological model. To demonstrate the capabilities of this so called tunneling model, acoustic and thermal properties of insulating amorphous solids are briefly discussed.

Amorphous solid carbon dioxide
The Journal of Chemical Physics, 1987Carbon dioxide gas condensed at 10 K was found to form amorphous solid films whose infrared spectra differ substantially from those of crystalline CO2. With the help of a sample of 13C-enriched CO2, the fundamental absorption bands of different isotopic species of CO2 in the spectra of the amorphous solid, crystalline solid, and of CO2 dispersed in ...

Lattice vibrations, or phonons, in crystalline solids have been studied since the beginning of the century1. Until about 15 years ago they were seen experimentally rather indirectly but since then, inelastic neutron scattering has made the direct measurement of phonon dispersion curves almost routine.2 The phonons in a solid are a basic ingredient in ...
