| Abstract Scope |
High-entropy carbides (HECs) have attracted considerable research interest owing to the significant increase in potential compositions and unique combinations of properties in many of the known systems. Significant advancements have been made in computational modeling of HECs to identify single-phase materials and predict their properties in advance. Key research in machine learning, density functional theory, and ab-initio molecular dynamics will be presented. However, significant barriers exist toward the scale-up of HEC fabrication beyond the pilot research and development scale. Currently, all reported fabrications of HEC materials use processes that are not amenable to manufacturing HECs on the scale a materials supply company requires. Herein, two commercially relevant routes to producing HEC feedstocks are demonstrated: cold crucible induction melting and spray drying. Consolidation of the as-spray dried HEC feedstock is demonstrated. Several analyses of the cold crucible bar, spray dried particles, and densified sample are utilized to validate each processing route. |
