| Outline of Final Research Achievements |
The present study has succeeded in fabricating high-entropy bulk metallic glasses (HE-BMGs) as represented by Fe25Co25Ni25(B, Si)25 alloy with a critical diameter of 1.5 mm for forming glassy phase. The alloys were developed by applying a concept of confusion principle that has effectively been utilized for the alloy development of high-entropy (H-E) alloys of multicomponent equi-atomic compositions. Furthermore, a first success in fabricating H-E alloys with hexagonal dense-packed structure was reported by fabricating YGdTbDyLu and GdTbDyTmLu alloys. In the 5-year project, alloy designs of the H-E and relevant alloys have been established based on statistic analysis.
