Glass Forming Ability in Systems with Competing Orderings [PDF]

Physical Review X, 2018
Some liquids, if cooled rapidly enough to avoid crystallization, can be frozen into a nonergodic glassy state. The tendency for a material to form a glass when quenched is called “glass-forming ability,” and it is of key significance both fundamentally ...

Thermodynamically-guided machine learning modelling for predicting the glass-forming ability of bulk metallic glasses [PDF]

Scientific Reports, 2022
Glass-forming ability (GFA) of bulk metallic glasses (BMGs) is a determinant parameter which has been significantly studied. GFA improvements could be achieved through trial-and-error experiments, as a tedious work, or by using developed predicting tools.

Glass-Forming Ability and Thermal Properties of Al₇₀Fe_12.5V_12.5X₅(X = Zr, Nb, Ni) Amorphous Alloys via Minor Alloying Additions [PDF]

Nanomaterials, 2021
The Al70Fe12.5V12.5Ni5, Al70Fe12.5V12.5Zr5 and Al70Fe12.5V12.5Nb5 alloys were prepared via mechanical alloying. The influence of Zr, Nb or Ni addition on the glass-forming ability of Al-Fe-V amorphous alloys have been investigated.

The glass-forming ability of model metal-metalloid alloys [PDF]

The Journal of Chemical Physics, 2014
Bulk metallic glasses (BMGs) are amorphous alloys with desirable mechanical properties and processing capabilities. To date, the design of new BMGs has largely employed empirical rules and trial-and-error experimental approaches.

On the glass forming ability of liquid alloys. [PDF]

Sci Technol Adv Mater, 2008
By using the concepts of the short-range order (SRO) and middle-range order (MRO) characterizing structures, an attempt has been made to describe the glass forming ability (GFA) of liquid alloys. This includes the effect of more than two kinds of SRO in the liquid caused by the addition of second and third elements to a metallic solvent.

Evaluation of glass forming ability of alloys [PDF]

China Foundry, 2005
Key step of exploiting a new type BMG (Bulk Metallic Glass) is quickly judging GFA (Glass Forming Ability) of the alloys. The mole melting heats of BMGs are calculated using the weighted averages principle. The reliability and limitation of Trg criterion
