Liquid -to-glass transition in bulk glass-forming Cu55-xZr45Agx alloys using molecular dynamic simulations

EPJ Web of Conferences, 2011
We report results from molecular dynamics (MD) studies concerning the microscopic structure of the ternary, bulk metallic glass-forming Cu55-x Zr45Agx (x=0,10,20) alloys using tight-binding potentials. Understanding of the nature of Glass Forming Ability

Enhancement of glass-forming ability of CoFeBSiNb bulk glassy alloys with excellent soft-magnetic properties and superhigh strength

, 2011
Co-based bulk glassy alloys with diameters up to 4.5 mm were formed in Co46Fe20B22+xSi6-xNb6 (x = 0-2) system. The increase of B to Si concentration ratio is effective in improving the glass-forming ability. In addition to high glass-forming ability, the

Free volume: An indicator of the glass-forming ability in binary alloys

AIP Advances, 2017
As a specific concept, free volume is proposed to affect the glass formation in alloys, while such issue remains unsolved, because free volume itself is ambiguous and elusive.

Influences of preparation techniques on glass-forming ability of Fe-P-B-Si-C amorphous alloys

, 2018
It has been widely accepted that the ultrafast cooling rate is required for the glass formation of amorphous alloys. Here, the larger glass-forming ability (GFA) of Fe76P5(B0.5Si0.3C0.2)(19) amorphous alloy was achieved by water quenching at lower ...

Glass-forming Ability, Configuron Localization and Electrical Conductivity

Glass-forming ability (GFA) is traditionally discussed in terms of atomic mobility, thermodynamics, and kinetic suppression of crystallisation. However, correlations between GFA and electrical conductivity across both metallic and non-metallic amorphous ...

A critical analysis of the glass-forming ability of alloys

, 2009
Several empirical rules have been proposed during the past few years to synthesize bulk metallic glasses. But, the real reasons for the improved glass-forming ability of these alloys are still not clear and the ability to design alloy compositions to ...
