The formation of clusters was analyzed in a topologically disordered network of bonds of
amorphous silica (SiO2) based on the Angell model of broken bonds termed configurons. It …

Transformation of glasses into liquids is discussed in terms of configuron (broken chemical
bond or transformation of an atom from one to another atomic shell) percolation theory with …

The atomic structure variations on cooling, vitrification and crystallization processes in liquid
metals face centered cubic (FCC) Cu are simulated in the present work in comparison with …

The knowledge of atomic structure for liquids, especially for liquid alloys with complex crystal
structure and high liquidus temperatures, remains poorly understood. In this work, we have …

This is an overview of recent findings on the structural changes observed upon heating,
including crystallization processes in conventional metallic glasses, bulk metallic glasses …

We develop the notion that amorphous substances undergo reversible configurational
structural changes accompanied by local expansion and compression (atom delocalization) …

The glass formation ability of an alloy depends on two competing processes: glass-
transition, on one hand, and crystal nucleation and growth, on the other hand. While these …

A second melting temperature occurs at a temperature Tn+ higher than Tm in glass-forming
melts after heating them from their glassy state. The melting entropy is reduced or increased …

The rapid development of technology, industry and aerospace manufacturing requires the
search for new materials with high strength, low weight and corrosion resistance. Graphene …

Structural mechanisms causing local coordination changes during crystallization and
vitrification in dilute face-centered-cubic (FCC) alloys was investigated using model Al-Sm …
