Insight into thermodynamics and corrosion behavior of Al-Ni-Gd glassy alloys from atomic structure

► Main peak shoulder in XRD curves of Al-Ni-Gd glasses rose with increasing cNi. ► Contraction degree of glasses during crystallization increased with cNi. ► Metastable peak in polarization curves of glasses increased with cNi. ► Thermal and corrosion behavior of glasses was elucidated by Al-Ni bond.
