Glass formation in binary alloys with different atomic symmetries [PDF]
Phys. Rev. Materials 4, 105602 (2020), 2020 Prediction of the glass forming ability (GFA) of alloys remains a major challenge. We are not able to predict the composition dependence of the GFA of even binary alloys. To investigate the effect of each element's propensity to form particular crystal structures on glass formation, we focus on binary alloys composed of elements with the same size, but
