This article presents an overview of three challenging issues that are currently being
debated in the community researching on the evolution of amorphous structures in metallic …

The viscosity and its temperature dependence, the fragility, are key properties of a liquid. A
low fragility is believed to promote the formation of metallic glasses. Yet, the fragility remains …

Glasses formed from nano-and microparticles form a fascinating testing ground to explore
and understand the origins of vitrification. For atomic and molecular glasses, a wide range of …

The dynamical behaviour of liquids is frequently characterized by the fragility, which can be
defined from the temperature dependence of the shear viscosity, η (ref.). For a strong liquid …

Fragility constitutes a major parameter of supercooled liquids. The phenomenological
definition of this quantity is related to the rate of a change of the shear viscosity η at the glass …

Microalloying is an effective approach to improve the macroscopic properties of alloys. For
understanding the microalloying effect on the dynamic behavior of metallic glass-forming …

The response to different stress amplitudes at temperatures below the glass transition
temperature is analyzed by mechanical oscillatory excitation of Pd 40 Ni 40 P 20 metallic …

We analyze the crystal growth kinetics of rapidly solidifying glass-forming Cu 50 Zr 50 alloy
melts. Formulating a dendrite growth model we predict all features of crystallization kinetics …

Cu-Zr is one of the best binary metallic glass formers. Here, new data on the enthalpy and
specific heat difference between undercooled melt and crystal phases are provided for the …

Within the shoving model of the glass transition, the relaxation time and the viscosity are
related to the local cage rigidity. This approach can be extended down to the atomic level in …
