IUCRC Phase III University of Tennessee, Knoxville (UTK): Manufacturing and Materials Joining Innovation Center (Ma2JIC)

制造和材料连接创新中心（Ma2JIC）是一个由多所大学组成的联盟，通过促进科学发现和应用，领导材料连接和金属增材制造研究。该中心还教育下一代科学家和工程师，他们将开发新的先进制造技术和工艺创新，以重建美国国内制造业的竞争力。考虑到材料连接对于制造对健康、安全、国家安全和多个行业连续性至关重要的产品的重要性，Ma2JIC为美国经济和国防的多个国家利益部门提供服务。该中心为政府合作伙伴、工业界和大学教师和学生提供了一个高度协作的研究环境，以促进材料连接和增材制造基础知识的发展和应用。该中心还为训练有素和多样化的科学和工程劳动力的教育提供平台。Ma2JIC对研发的关注转化为行业成员和消费者的利益。所有站点之间的协调努力提高了公众意识、科学素养和多样化的STEM管道。基于其庞大而多样化的行业成员的需求，Ma2JIC支持以下三个重点领域的研究：(1)材料和接头性能；(2)增材制造、工艺开发和控制；(3)材料、微观结构和可焊性和可打印性。材料和接头性能重点关注材料和制造工艺对制造或印刷部件的机械、功能和环境性能的影响，特别是在提高可靠性、降低成本和延长关键基础设施的使用寿命方面。增材制造、工艺开发和控制重点领域解决了连接和增材制造（AM）工艺、机器人和控制方面的基本挑战，以及连接和AM的集成计算材料工程（ICME）框架。最后，材料、微结构、可焊性和可印刷性重点领域寻求发展基本的理解和测试能力，以使材料的评估和开发更适合先进的连接和制造工艺。田纳西大学诺克斯维尔分校（UTK）基地以其独特的研究能力和基础设施资源补充了中心内的合作研究，用于进行各种表征研究，并建立了机床研究中心（MTRC），拥有铣削和增材制造系统。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。

The Manufacturing and Materials Joining Innovation Center (Ma2JIC) is a multi-university consortium leading materials joining and metal additive manufacturing research by fostering and translating scientific discovery to application. The Center also educates the next generation of scientists and engineers that will develop new advanced manufacturing technologies and process innovations to rebuild the competitiveness of U.S. domestic manufacturing. Given the importance of materials joining for the manufacturing of products that are critical to health, safety, national security, and the continuity of multiple industries, Ma2JIC serves multiple sectors of national interest for the U.S. economy and defense. The center provides a highly collaborative research environment among government partners, industry, and university faculty and students to promote the development and application of fundamental knowledge in materials joining and additive manufacturing. The Center also serves as a platform for the education of a well-trained and diverse scientific and engineering workforce. Ma2JIC’s primary focus on research and development translates into industry members' and consumers' benefit. The coordinated effort across all sites increases public awareness, scientific literacy and a diverse STEM pipeline.Based on the needs of its large and diverse industrial membership, Ma2JIC supports research in the following three thrust areas: (1) Materials & Joints Performance, (2) Additive Manufacturing, Process Development & Control, and (3) Materials, Microstructure & Weldability & Printability. The Materials & Joints Performance thrust focuses on the effect of materials and manufacturing processes on the mechanical, functional and environmental performance of manufactured or printed components, especially with regard to improved reliability, cost reduction and extension of service life of critical infrastructure. The Additive Manufacturing, Process Development & Control thrust area addresses fundamental challenges in joining and additive manufacturing (AM) processes, robotics, and control, as well as integrated computational materials engineering (ICME) frameworks for joining and AM. Finally, the Materials, Microstructure & Weldability & Printability thrust area seeks to develop fundamental understanding and testing capabilities to enable evaluation and development of materials more amenable to advanced joining and manufacturing processes. The University of Tennessee, Knoxville (UTK) site complements collaborative research within the center with its unique research capabilities and infrastructure resources for conducting various characterization studies and a Machine Tool Research Center (MTRC) with milling and additive manufacturing systems.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.
