Metallic glasses (MG) represent an interesting group of materials as they possess outstanding physical, chemical and mechanical properties compared to their crystalline counterparts. This paper reviews the synergistic influence of Ni and Nb elements on thermal stability of supercooled liquid and corrosion resistance of as-cast Cu-Zr(Hf)-Ti-Ni-Nb bulk metallic glasses (BMGs). Additionally, in-situ second phase reinforced Cu-based BMG composites with high corrosion resistance and excellent mechanical properties are investigated. On the other hand, this paper reports the development of ultra-high corrosion resistant Ni-based metallic glasses at high temperatures for their potential applications. Corrosion resistance and XPS analysis of the Ni free Ti-based BMG are also introduced.
