This award funds planning activities at the University of Texas Rio Grande Valley (UTRGV) for a proposed new three-site industry university cooperative research center (IUCRC), the Center to Accelerate Recipe Development for Additive Manufacturing of Metals (CARDAMOM). CARDAMOM is led by the University of Nebraska-Lincoln in partnership with the University of Texas Rio Grande Valley, and the University of Alabama. Metal additive manufacturing (AM), also known as metal 3D printing, is transforming manufacturing within the United States and around the world. This new disruptive technology has already resulted in several success stories, primarily within the aerospace and biomedical sectors. However, further expansion to the greater manufacturing community is impeded by limitations in powder feedstocks, a lack of access to flexible and comprehensive metal AM research and production facilities, and a workforce with limited AM design experience. CARDAMOM proposes to address these research needs by assisting industry members along the entire “powder-to-part” development cycle to address fundamental research questions with a view toward final engineering applications. In addition, the team will address societal impacts of education and workforce development which will have a significant impact on the training of students from diverse backgrounds and educational institutions. Eventually, CARDAMOM aims to be a steady provider of high-quality engineers and technicians to manufacturers and government research laboratories. The mission of CARDAMOM is to transform the manufacturing of high-performance, quality metallic components created with AM via active engagement with Center industry members. With respect to the technological impacts, CARDAMOM will pursue multiple thrusts in order to: develop methods for production of AM feedstocks for new alloys; develop new methods and techniques to understand and interpret in situ measurement data; use advanced characterization to provide 3D microstructural and nanostructural information that connects processing methods to component performance; develop new computational methods to predict and understand microstructural development, leading to better ways to design new materials and processes; develop innovative measurements to quantify laser-metal interactions; use advanced metrology and NDE to enhance AM build quality; develop new data analytical (machine learning) approaches for data interpretation and scientific insight. CARDAMOM will engage potential members across the full supply chain, including equipment manufacturers, aerospace and defense companies, tool and die producers, materials development companies, process optimization designers, and government laboratories. At UTRGV, the team will leverage equipment and resources at the Center for Advanced Manufacturing which hosts metal AM equipment and custom-built open-platform AM processes including: laser-assisted cold spray, open-platform powder bed fusion equipment, 8 kW open-platform laser DED, robotic friction stir weld, and robotic wire arc. UTRGV thrusts include: 1) high deposition rate convergent laser DED processes, 2) additive manufacturing of refractory metal alloys for high-temperature applications, 3) in-situ induction heat treatment for laser additive manufacturing of high-entropy alloys, 4) recipe development for LPBF and laser DED to fabricate metal boride for energy, tool and die industries.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.

该奖项资助德克萨斯大学里奥格兰德河谷分校 (UTRGV) 拟议的新三地工业大学合作研究中心 (IUCRC) 的规划活动，该中心由加速金属增材制造配方开发中心 (CARDAMOM) 领导。由内布拉斯加大学林肯分校与德克萨斯大学里奥格兰德河谷分校和阿拉巴马大学合作开发的金属增材制造 (AM)（也称为金属 3D 打印）正在改变美国的制造业。这种新的颠覆性技术已经取得了多个成功案例，主要是在航空航天和生物医学领域。然而，由于粉末原料的限制以及缺乏灵活和全面的途径，进一步扩展到更大的制造领域受到阻碍。 CARDAMOM 提议通过在整个“粉末到零件”开发周期中协助行业成员解决基础研究问题，以实现最终的工程设计，从而满足这些研究需求。应用中。此外，该团队还将解决教育和劳动力发展的社会影响，这将对来自不同背景和教育机构的学生的培训产生重大影响，最终，CARDAMO 的目标是成为制造商和技术人员的稳定提供者。 CARDAMOM 的使命是通过与中心行业成员的积极合作，改变增材制造高性能、优质金属部件的制造方式。用于增材制造生产新合金原料；开发新方法和技术来理解和解释原位测量数据；使用先进的表征来提供将加工方法与部件性能联系起来的新计算方法，从而预测和理解微观结构的发展；更好的方法来设计新材料和工艺；开发创新的测量方法来量化激光与金属的相互作用；使用先进的计量学和无损检测来提高增材制造的质量；开发新的数据分析（机器学习）方法来进行数据解释和科学洞察。吸引整个供应链中的潜在成员，包括设备制造商、航空航天和国防公司、工具和模具生产商、材料开发公司、工艺优化设计师和政府实验室。在 UTRGV，该团队将利用先进中心的设备和资源。拥有金属增材制造设备和定制开放平台增材制造工艺的制造业，包括：激光辅助冷喷涂、开放平台粉末床熔合设备、8 kW 开放平台激光 DED、机器人搅拌摩擦焊和机器人电弧焊。重点包括：1) 高沉积速率会聚激光 DED 工艺，2) 用于高温应用的难熔金属合金的增材制造，3) 用于高熵合金激光增材制造的原位感应热处理，4) 配方开发LPBF 和激光 DED 为能源、工具和模具行业制造金属硼化物。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查进行评估，被认为值得支持标准。
