Abstract
•Pd41.25Ni41.25P17.5 alloy has a negative heat of mixing.•Amorphous phase separation in Pd41.25Ni41.25P17.5 BMGs•Small angle X-ray scattering•Interference peak at small q range•Porod law at large q range to confirm amorphous spinodal decomposition
Pd41.25Ni41.25P17.5 bulk metallic glasses (BMGs) undergo phase separation despite the fact that the alloy system has a negative heat of mixing. By employing the techniques of small angle X-ray scattering (SAXS), it was found that the phase separation is consistent with a spinodal mechanism. Its occurrence is attributed to unique short-range orders in the amorphous (or liquid) state of the BMGs.
