[MIS23-06] Melting and Solidification Behaviors in High Entropy Alloys
Keywords:high entropy alloy, medium entropy alloy, solidification
HEAs can be classified some groups based on the taxonomy of HEAs and multicomponent alloys, where HEAs can grouped based on the main constituent element and the relationship between the main constituent elements and the position of periodic table. 3d-transition metal type high entropy alloys (3d-HEAs) were mainly constructed with the 3d-transition metal elements of Cr, Mn, Fe, Co, Ni, Cu and Al elements. The main constituent elements of refractory high entropy alloys (RHEAs) and HEAs for metallic biomaterials (bio-HEAs) were 4 (Ti, Zr, Hf), 5 (V, Nb, Ta), and 6 (Cr, Mo, W) group elements. HE Brasses and HE Bronzes were mainly constructed by Cu, Zn, Sn and Al elements. The crystal growth behavior during the solidification of thermal melt in 3d-HEAs, RHEAs, bio-HEAs, HE Bronzes and HE Brasses were discussed for clarifying the general tendency of the crystal growth behavior in HEAs.
