EXTENDED ABSTRACT: Noble metal-based superalloys, due to their excellent high-temperature stability, oxidation resistance, and corrosion resistance, are key materials for components in both military and civilian applications. However, the high cost of noble metals limits their broader application, and "reducing quantity while increasing efffciency" has long been the goal of new noble metal material research and development. The data-driven research approach faces the challenge of scarce experimental data for noble metals. By integrating high-throughput, multi-scale computational methods (multilevel physical model solving) with artiffcial intelligence (machine learning modeling), it is expected to address the inherent issues of limited research experience, long development cycles, and high costs in new precious metal material development. Based on this approach, we have developed several new types of nobel metal-based superalloys, which have passed critical experimental validations and evaluations. This has led to the initial formation of an AI-driven paradigm for the development of noble metal-based superalloys.
