Recent progress in criterions for glass forming ability

Effect of Pouring Temperature on Microstructure and Mechanical Properties of Zr-Based Amorphous Alloys

“…Generally, the atomic structure of amorphous alloys has features of short-range order and long-range disorder [5], so that the alloy often has high strength, high hardness [6,7], high corrosion resistance [8], and excellent magnetic properties [9]. Due to crystal defects, crystalline materials often suffer from disadvantages such as poor resistance to intense mechanical and thermal shock.…”

Prediction of the glass-forming ability of Fe–B binary alloys based on a continuum-field-multi-phase-field model

“…Although a lot of glass-forming ability (GFA) criteria based on characteristic temperatures [1][2][3][4] have been proposed to understand the amorphization mechanism of metallic alloys and predict alloy compositions that possess high GFA, there is lack of the explicit physical interpretation and universal validity for different alloy systems. Until now, the development of new bulk metallic glasses (BMGs) still relies heavily on the empirical rules and experimental exploration.…”

Y and Er minor addition effect on glass forming ability of a Ni–Nb–Zr alloy

“…RE elements with larger atomic sizes than other elements of the alloy may stabilize the super cooled liquid or either act as oxygen scavenger and consequently improve the GFA [9]. From the practical aspect, the highest GFAs are correlated with the largest critical thickness or the lowest critical cooling rates to form a glass; however, it is difficult to measure such parameter precisely and there is no standard definition for GFA up to now [10].…”
