Shanghai Artificial Intelligence Laboratory, in collaboration with the Institute of Metal Research (CAS), Suzhou National Laboratory, and Shanghai Electric, has released AlloyEvo, a self-evolving alloy design expert model. After only one experimental iteration, the model designed a 3D-printed engineering titanium alloy with a tensile strength of 1817 MPa (a 12.8% improvement over the 1611 MPa highest benchmark) and a uniform elongation of 5%, matching the benchmark. The alloy was physically validated using an ultra-high-strength aerospace load-bearing bolt. The model establishes a closed loop of design, evaluation, experience accumulation, and redesign: AlloyDes generates candidate compositions and process routes; AlloyLLM (trained on 280,000 papers and 16B tokens of corpus, covering 62 key properties across six major alloy classes, with 72.37% accuracy on 30 evaluations) predicts performance and analyzes mechanisms; and AlloyExp distills both successful and failed cases into reusable structured experience cards (first-round experience was reused across 17 subsequent iterations). Traditional high-end alloy R&D relies heavily on expert trial and error, with experience difficult to accumulate; the AI paradigm shifts much of the trial and error to the model side. The system has been integrated into the Shusheng Duanyan scientific discovery platform and can be extended to superalloys, special steels, rare earths, and other areas in the future. For powder buyers: AI design will significantly accelerate the pace at which new alloy grades emerge—shortening the cycle from laboratory to custom atomization at powder plants. A powder plant's ability to respond to multi-variety, small-batch trial powder production will become a key competitive differentiator. The composition-process combinations provided by the model (e.g., titanium alloy heat treatment schedules) can directly guide powder customers' process development. It is recommended to pursue joint custom powder validation with AI materials platforms and university teams to secure powder supply qualification for next-generation grades.
