This Designing Materials to Revolutionize and Engineer our Future (DMREF) project aims to revolutionize the creation of novel engineering alloys by focusing on the relationship between the process of production and the material's resultant microstructure - the internal structure invisible to the naked eye. This relationship is a crucial but less-explored segment of the material science lifecycle, yet directly connects processing to performance. Using cutting-edge machine learning and data science, the project team will build a platform, named as DRAGONS (Data-driven Recursive AI-powered Generator of Optimized Nanostructured Superalloys), to discover these connections, enabling more nuanced control over material production. DRAGONS will prescribe ideal processing conditions to achieve a specific material microstructure. This project carries broad significance, with the potential to drive advancements in diverse sectors that rely on novel materials including electronics, healthcare, energy, and transportation. Additionally, the project's educational outreach activities aim to inspire the next generation of scientists and engineers by providing a more diverse, inclusive, and sustainable pathway into these fields. Hence, this research carries potential to catalyze scientific advancement, foster economic growth, and enhance educational outcomes.This DMREF project focuses on harnessing machine learning and data science to advance understanding of the processing-microstructure relationships in the production of novel materials, a key, yet underexplored facet of the Materials Genome Initiative (MGI). The research team will develop a data-driven platform, named as Data-driven Recursive AI-powered Generator of Optimized Nanostructured Superalloys (DRAGONS), to demystify the complex relationships inherent in the creation of multi-phase, heterogeneous nanostructured materials (HNMs). DRAGONS will utilize predictive models to interpret microstructure attributes based on given processing conditions and, in a reciprocal manner, provide processing parameters required to generate a predefined microstructure. Capitalizing on expertise in magnetron sputtering and heat treatment (MS+HT), the research team aims to engineer intricate heterogeneous designs in Ni-based superalloys. An iterative research framework encompasses synthesis and microstructural design, microstructure characterization, atomistic simulation, and mesoscale modeling, and each cycle will refine DRAGONS, fostering stronger links between processing descriptors and microstructure features. The broader impacts of this work span the potential to reshape engineered alloy development and to foster collaborations with NIST scientists. Furthermore, educational programs targeted at developing a diverse, skilled workforce in materials engineering underscore the project's commitment to society.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个设计材料以革新和工程我们的未来（DMREF）项目旨在通过关注生产过程与材料的最终微观结构（肉眼看不见的内部结构）之间的关系，彻底改变新型工程合金的创造。这种关系是材料科学生命周期中至关重要但较少探索的部分，但将加工与性能直接联系起来。利用尖端的机器学习和数据科学，项目团队将建立一个名为DRAGONS（数据驱动的递归人工智能驱动的优化纳米结构高温合金生成器）的平台，以发现这些联系，从而对材料生产进行更细致的控制。龙将规定理想的加工条件，以实现特定的材料微观结构。该项目具有广泛的意义，有可能推动电子、医疗、能源和交通等依赖新型材料的各个领域的进步。此外，该项目的教育推广活动旨在通过提供更多样化、包容性和可持续的途径，激励下一代科学家和工程师进入这些领域。因此，这项研究具有催化科学进步、促进经济增长和提高教育成果的潜力。这个DMREF项目的重点是利用机器学习和数据科学来推进对新材料生产过程中微观结构关系的理解，这是材料基因组计划（MGI）的一个关键但尚未充分探索的方面。该研究团队将开发一个数据驱动平台，名为“数据驱动递归人工智能驱动的优化纳米结构高温合金发生器”（DRAGONS），以揭开多相、非均质纳米结构材料（hnm）制造过程中固有的复杂关系的面纱。DRAGONS将利用预测模型根据给定的加工条件解释微观结构属性，并以互惠的方式提供生成预定义微观结构所需的加工参数。利用磁控溅射和热处理（MS+HT）方面的专业知识，研究团队的目标是在镍基高温合金中设计复杂的异质设计。一个迭代的研究框架包括合成和微结构设计、微结构表征、原子模拟和中尺度建模，每个周期都将改进DRAGONS，在加工描述符和微结构特征之间建立更强的联系。这项工作的广泛影响跨越了重塑工程合金发展的潜力，并促进了与NIST科学家的合作。此外，旨在培养材料工程领域多样化、高技能劳动力的教育项目强调了该项目对社会的承诺。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
