IUCRC Phase III Pennsylvania State University (PSU): Manufacturing and Materials Joining Innovation Center (Ma2JIC)

制造与材料连接创新中心（Ma2JIC）是一个专注于材料连接和金属增材制造研究的多所大学联盟。该中心培育科学发现并将其转化为应用，同时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。鉴于材料连接对于制造对健康、安全、国家安全和多个行业的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。该中心是一个教育训练有素和多样化的科学和工程劳动力的平台。Ma2JIC的主要重点是研究和开发，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和科学素养。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，特别是因为它们与提高可靠性、降低成本和延长关键基础设施的使用寿命有关。增材制造、工艺开发和控制重点解决了连接和增材制造（AM）工艺、机器人和控制以及连接和AM的集成计算材料工程（ICME）框架中的基本挑战。最后，材料、微观结构、可焊性和可打印性的重点是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。宾夕法尼亚州立大学是Ma2JIC的天然合作伙伴，在材料可焊性、制造和连接工艺开发、材料性能、建模创新和增材制造方面具有互补能力。除了增强其现有优势外，宾夕法尼亚州立大学还将带来新的能力和研究重点领域，以扩大Ma2JIC的项目范围和行业合作伙伴。宾夕法尼亚州立大学在粉末冶金、陶瓷和塑料加工方面具有历史优势。虽然这些重点领域补充了当前Ma2JIC的研究重点，但它们也允许扩展相关先进制造工艺的能力和研究，并促进多材料系统集成到现有和新产品形式中，为行业合作伙伴提供服务。这些能力也将补充Ma2JIC的行业合作伙伴基础，并在相关制造领域带来新的行业合作伙伴，如材料和航空零部件供应商。未来的工作将建立在建模和材料表征的基础上，以发展涉及多材料的新研究。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 focused on materials joining and metal additive manufacturing research. The Center fosters and translates scientific discovery to application while educating 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 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 is a platform for the education of a well-trained and diverse scientific and engineering workforce. Ma2JIC’s primary focus is on research and development that translates to industry members' and consumers' benefit. The coordinated effort across all sites increases public awareness and scientific literacy. 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, in particular as they relate to improved reliability, cost reduction and the extension of the service life of critical infrastruture. The Additive Manufacturing, Process Development & Control thrust 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 seeks to develop fundamental understanding and testing capabilities to enable evaluation and development of materials more amenable to advanced joining and manufacturing processes. Pennsylvania State University is a natural partner in Ma2JIC and brings complementary capabilities in materials weldability, manufacturing and joining process development, materials performance, modeling innovation, and additive manufacturing. In addition to enhancing its existing strengths, Penn State will also bring new capabilities and research focus areas to expand the range of projects and industry partners affiliated with Ma2JIC. Penn State has historical strengths in powder metallurgy, and ceramic and plastics processing. While these focus areas complement the current Ma2JIC research thrusts, they also allow for an expansion of capabilities and research into related advanced manufacturing processes and promote the integration of multi-material systems into existing and new product forms for the industry partners. These capabilities will also compliment the industry partner base within Ma2JIC and bring new industry partners in related manufacturing areas, such as materials and aerospace parts suppliers. Future work will build upon modeling and material characterization to develop new research involving multi-materials.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.
