چکیده
The effect of similar atom substitution on the glass forming ability (GFA) Al86Ni9(Y, Sm)5 (x = (0, 1, 1.5, 2, 3, 4, 5)) metallic glasses (MGs) was explored basis theory Fermi sphere-Brillouin zone interaction. Similar (Sm) mainly affects static structure between Al atoms and Y atoms, changing diameter pseudo-Brillouin (KP). Its level Brillouin size is characterized with spectroscopy experiments. |δ|=|KP – 2KF| criterion used to evaluate Sm element GFA. This can help us obtain optimal GFA composition (Al86Ni9Y3.5Sm1.5) amorphous alloys, confirmed also by experimental results.

Effects of similar-element-substitution on the glass-forming ability and mechanical behaviors of Ti-Cu-Zr-Pd bulk metallic glasses
The Ti41Cu31Zr10Pd13 (at.%) metallic glasses are promising for bone-implantation applications due to their exceptional bio-compatibility. However, Pd, as a noble element, keeps the fabrication cost high and prevents the industrial sale production of these alloys. Searching for replacements with comparable glass-forming ability and ductility but lower cost turns out to be imperative. In this art...

Computational studies of the glass-forming ability of model bulk metallic glasses.
Bulk metallic glasses (BMGs) are produced by rapidly thermally quenching supercooled liquid metal alloys below the glass transition temperature at rates much faster than the critical cooling rate R(c) below which crystallization occurs. The glass-forming ability of BMGs increases with decreasing R(c), and thus good glass-formers possess small values of R(c). We perform molecular dynamics simula...
