Combinatorial measurement of critical cooling rates in aluminum-base metallic glass forming alloys

Scientific Reports, 2021
Direct measurement of critical cooling rates has been challenging and only determined for a minute fraction of the reported metallic glass forming alloys.

Glass-forming ability of elemental zirconium [PDF]

Physical Review B, 2020
We report large-scale molecular dynamics simulations of the glass formation from the liquid phase and homogeneous nucleation phenomena of pure zirconium. For this purpose, we have built a modified embedded atom model potential in order to reproduce relevant structural, dynamic, and thermodynamic properties from ab initio and experimental data near the ...

Preparation and Property of Cu50Zr50-xYx Amorphous Alloy

International Journal of Electrochemical Science, 2017
Cu-Zr bulk metallic glasses (BMGs) have aroused wide concern recently as they have good glass forming ability, excellent mechanical property, high corrosion resistance and relatively low cost. In this research, different amount of rare earth Y were added

Glass-forming ability of soda lime borate liquids [PDF]

Journal of Non-Crystalline Solids, 2012
We investigate the composition dependence of glass-forming ability (GFA) of a series of iron-containing soda lime borate liquids by substituting Na2O for B2O3. We have characterized GFA by measuring the glass stability against crystallization using a differential scanning calorimeter (DSC). The results show that the GFA decreases when substituting Na2O

Excessively High Vapor Pressure of Al-based Amorphous Alloys

Metals, 2015
Aluminum-based amorphous alloys exhibited an abnormally high vapor pressure at their approximate glass transition temperatures. The vapor pressure was confirmed by the formation of Al nanocrystallites from condensation, which was attributed to weight ...

Atomic-Scale Mechanisms of the Glass-Forming Ability in Metallic Glasses

Physical Review Letters, 2012
The issue, composition dependence of glass-forming ability (GFA) in metallic glasses (MG), has been investigated by systematic experimental measurements coupled with theoretical calculations in Cu-Zr and Ni-Nb alloy systems. It is found that the atomic-level packing efficiency strongly relates to their GFA.

Thermodynamics and the Glass Forming Ability of Alloys [PDF]

Journal of Alloys and Compounds, 2011
Bulk metallic glasses (BMGs) have received a great deal of attention due to scientific and technological interest ever since the first successful synthesis of an amorphous phase in the Au–Si system in 1960 (Klement et al., 1960). There has been a lot of interest to identify parameters to assess the glass forming ability (GFA) of various alloy systems ...
