| Abstract: |
| Special metallurgy, a significant branch of the metallurgical discipline, is derived from the application of physical external field or new medium in metallurgical process. It represents one of the most dynamic frontier areas in metallurgy and holds particular importance for overcoming the traditional "dual carbon" technology bottleneck in metallurgy, strengthening metallurgical processes, and enhancing the level of metallurgical technology and equipment. In this paper, the definition, principle, method and classification of special metallurgy were systematically explored. The development history and evolution process of special metallurgy were traced. The progress and breakthrough made by China in special metallurgy fields such as microwave metallurgy, self-propagating high-temperature synthesis (SHS), ultrasonic metallurgy, hypergravity metallurgy, vacuum and relative vacuum metallurgy, chlorination metallurgy, oxygen-enriched metallurgy (smelting), pressure hydrometallurgy and electroslag metallurgy were especially introduced. The scientific challenges faced by the future development of special metallurgy were summarized, and the potential future application scenarios and development prospects were discussed. |
