They are often produced by casting and rapid quenching techniques, when nucleation and growth of crystalline phases are suppressed during cooling of liquid alloys. In addition, amorphous alloys can be obtained by several other methods such as electro-deposition, physical and chemical vapor deposition, spray deposition, solid state reactions and mechanical milling. In spite of their non-crystalline structure, the attractive interactions and the size differences between atomic species constituting an amorphous alloy, lead to a short and medium-range order characterized by clusters of atoms which connect to fill the space nearly as densely as their crystalline counterparts. The amorphous structure leads to a combination of exceptional mechanical, electrochemical, tribological and magnetic properties which are often superior to those of their crystalline counterparts and therefore attractive for “high-end” applications. Thus, amorphous alloys have emerged with the progress in Materials Science as an important new category of materials with unique properties, unusual structures and high potential for cutting edge applications in various industrial sectors.

The simulation methods of melting temperature, enthalpy, specific heat, surface tension, diffusion coefficient and viscosity are introduced and the simulated results are summarized. By comparing the experimental results and various theoretical models, the temperature and the composition dependences of the thermophysical properties in undercooled regime are discussed. http://www.mdpi.com/1422-0067/12/1/278/ Mon, 10 Jan 2011 00:00:00 CET International Journal of Molecular Sciences 2011-01-10 12 1 Review 278 316 1422-0067 Thermophysical Properties of Undercooled Alloys: An Overview of the Molecular Simulation Approaches 2011-01-10 doi: 10.3390/ijms12010278 Yong J. Lv Min Chen http://www.mdpi.com/1422-0067/11/12/5184/ We review our recent study on the polyamorphism of the liquid and glass states in a monatomic system, a two-scale spherical-symmetric Jagla model with both attractive and repulsive interactions. This potential with a parametrization for which crystallization can be avoided and both the glass transition and the liquid-liquid phase transition are clearly separated, displays water-like anomalies as well as polyamorphism in both liquid and glassy states, providing a unique opportunity to study the interplay between the liquid-liquid phase transition and the glass transition. Our study on a simple model may be useful in understanding recent studies of polyamorphism in metallic glasses. http://www.mdpi.com/1422-0067/11/12/5184/ Thu, 16 Dec 2010 00:00:00 CET International Journal of Molecular Sciences 2010-12-16 11 12 Review 5184 5200 1422-0067 Liquid-Liquid Phase Transition and Glass Transition in a Monoatomic Model System 2010-12-16 doi: 10.3390/ijms11125184 Limei Xu Sergey V.
