| This paper aims to review our recent data on the development researches and application examples of bulk glassy alloys. Very recently, the glass-forming ability of metallic alloys is significantly enhanced by further multiplication of alloy components based on the three component rules for bulk glass formation. The maximum diameter for glass formation exceeds 10 mm in a variety of alloy systems such as Zr, Pd, Pt, Mg, La, Fe, Co, Ni and Cu bases. By use of high glass-forming ability, good castability, good printability and unique characteristics, application examples of bulk glassy alloys have been extended to much valuable fields in which conventional crystalline alloys cannot be used. These novel advantages for bulk glassy alloys allow us to conclude that bulk glassy alloys are used in much wider application fields in the near future. |
