In order to form a glass by cooling a liquid, the normal process of solid crystallization must be bypassed. Achieving that for a pure metal had seemed impossible — until pressure was applied to liquid germanium. Glasses come in many forms. For the specific case of metallic glasses, multiple components are usually required to avoid crystallization during normal liquid cooling. (The one notable exception is the two-component metallic glass Zr50Cu50.) Now Bhat et al. have made use of recent…

Size-dependent structure transformation from amorphous phase to crystal
A size-dependent crystal growth mechanism is studied by molecular dynamics simulations. The amorphous silver firstly deposits under the coordinated actions between the lattice mismatch and
Alternative approach to thermodynamic phase transitions
One of the major open problems in theoretical physics is the lack of a consistent quantum gravity theory. Recent developments in our knowledge on thermodynamic phase transitions of black holes and
Implications of new phase transitions approach onto specific black holes
Among many open questions in theoretical physics, consistent quantum gravity theory is still a major issue to be solved. Recent major works in phase transitions of black holes (BH) can be helpful for
Double-Win Properties Response of Mechanical and Hydrogen Absorption in Melt-Spun Ti-Zr-Ni-Cr Amorphous Metals
The effect of spinning rates on mechanical properties and hydrogen absorption/desorption properties of Ti47Zr31Ni14Cr8 amorphous ribbons have been investigated in the present work. A fully amorphous


Vitrification of a monatomic metallic liquid
The insights gained in a recent molecular dynamics simulation study are applied to create conditions for successful vitrification of metallic liquid germanium and provide micrographic evidence for a rare polyamorphic transition preceding crystallization of the diamond cubic phase.
Under what conditions can a glass be formed
Summary Generally substances are more stable in a crystalline than in a glassy state. Therefore, to form a glass, crystallization must be bypassed. Under certain conditions, the melts of many
Formation of Crystal Nuclei in Liquid Metals
The known facts about nucleation phenomena in liquid metals are interpreted satisfactorily on the basis of the critical size and interfacial energy concepts. In large continuous masses nucleation is
