| Outline of Final Research Achievements |
An alloy design for high entropy alloys was established in the present study by combining thermodynamic calculations and valence election concentration control. Representative achievements were high entropy bulk metallic glass (HE-BMG) with critical diameter of 18 mm, and a single hcp and fcc HEA in Ir-Rh-Ru-W-Mo alloy system. Furthermore, precise thermodynamically calculations revealed that there exists a relationship of mixing entropy (Smix) being greater than configuration entropy (Sconfig) as Smix > Sconfig in some of existing HEAs. The present study revealed the truth of entropy, which is the basis of HEAs.
