Abstract Scope |
The efficient cluster packing model assumes solute-centered clusters for Metallic glass (MG) fabrication. However, pure-solvent clusters (PSCs) with high free energy have been found in Al and Fe-based marginal MGs. This study introduces two criteria—atomic topology and chemical affinity—for designing MGs with PSCs and develops a new Ti-based alloy system containing PSCs. The feasibility of producing Ti-based MGs with PSCs was confirmed through experiments and simulations. This study provides an overview of the structural concept, characteristics, and design methods of PSCs, which have not been previously reported. Ti-based MGs with PSCs from this study could be useful in catalysis and other functional applications due to soft atomic bonding and low activation energy. They could also be beneficial in biomedical applications due to their high Ti content compared to conventional MGs. |
