Abstract

The Ni₈₀P₂₀ metallic glass, with a relatively simple composition, was used as a model material to study the effect of pressure on the local atomic structure during the cooling process using molecular dynamics simulations. Various structural analysis methods, including Voronoi tessellation, revealed that increasing pressure (0–15 GPa) significantly enhances glass transition temperature (T_g) from 565 K to 765 K and promotes densification of the atomic structure. While the global short-range order, such as icosahedral configurations, remains relatively stable, pressure-induced shifts in atomic coordination and packing efficiency suggest enhanced mechanical strength and thermal stability. These findings provide valuable insights into the kinetics of amorphous phase formation of the alloy melt under pressure and its potential for optimizing the physical properties of metallic glasses for various applications.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
