Phase II IUCRC at Colorado School of Mines: Center for Manufacturing & Materials Joining Innovation Center (Ma2JIC)

制造和材料联合创新中心（Ma 2 JIC）致力于解决国家利益所在的现代制造业中的基础设施重建和创新材料应用问题。Ma 2 JIC中心在大学和工业合作伙伴之间建立了一个环境，促进了材料连接和增材制造领域基础知识的发展和应用，并为下一代科学家和工程师的教育提供了一个平台。作为自成立以来的网站之一，科罗拉多矿业学院（CSM）网站补充了该中心在创新焊接材料的设计和制造，焊接和连接工艺创新，焊接材料表征，以及能源，航空航天，石油和天然气和制造业的增材制造方面的独特专业知识和实验室设施。CSM工厂将寻求加强与其他中心工厂的合作，共同发展与焊接、连接和制造行业（无论大小）、国家实验室和政府机构的合作。Ma 2 JIC中心的优势在于能够缩小材料开发与制造业材料可焊性之间的差距，并从所有这些惊人的协同效应中获得最终的社会效益。Ma 2 JIC中心的研究重点是工艺创新、材料性能、增材制造、焊接性测试和评估将发展基本的理解，如材料四面体-“加工-微观结构-性能-性能”所描述的。 CSM Site的研究人员正在研究激光粉末床熔合AM制造产品的GTA和激光焊接性的基本方面，激光粉末床熔合和定向能量沉积AM产品的固化行为，以及用于电子束自由成形制造产品（包括金属基复合材料）微观结构优化的填充金属开发。正在尝试将反应合成粉末结合到用于基于激光和基于电子束的增材制造的管状线中。表面张力对AM沉积物的影响将被充分表征和理解，以进行过程控制。 另一个研究重点是设计和制造用于石油和天然气钻井作业的具有增强耐磨性和抗断裂性的热喷涂涂层。CSM工厂将继续研究和设计用于变形控制和残余应力缓解控制的低相变温度焊接（LTTW）耗材。这些计划预计将导致基础知识和实用技术的发展。CSM研究中心还致力于在智能焊接、搅拌摩擦加工、机器人技术、先进的中子和X射线表征以及数据驱动建模等方面开展跨大学和多行业合作。该奖项反映了NSF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) addresses the question of infrastructure rebuilding and innovative materials application in modern manufacturing which are of national interest. The Ma2JIC Center establishes an environment between universities and industrial partners that promotes the development and application of fundamental knowledge in the areas of materials joining and additive manufacturing and provides a platform for the education of the next generation of scientists and engineers. As one of the sites since its inception, the Colorado School of Mines (CSM) Site has complemented the Center with its unique expertise and laboratory facilities in the design and manufacturing of innovative welding materials, welding and joining process innovation, welding materials characterization, and additive manufacturing for the energy, aerospace, oil and gas, and manufacturing industries. The CSM Site will seek to intensify its collaborations with the other Center Sites to jointly develop collaborations with the welding, joining and manufacturing industries, large and small, national laboratories and government agencies. The strength of the Center is the ability of the group to close the gap between materials development and weldability for materials used in the manufacturing industry, with ultimate societal gain from all these amazing synergies.The Ma2JIC Center research thrusts of Process Innovation, Materials Performance, Additive Manufacturing, Weldability Testing and Evaluation will develop fundamental understanding as described by the materials tetrahedron - "Processing-Microstructure-Properties-Performance". CSM Site researchers are examining the fundamental aspects of GTA and Laser weldability of Laser-Powder bed fusion AM built products, solidification behavior of Laser-Powder bed fusion and Directed Energy Deposition AM products, and filler metal development for microstructural optimization in Electron Beam Freeform Fabrication products, including metal matrix composites. The incorporation of Reaction Synthesis powder into tubular wires for both laser-based and electron beam-based additive manufacturing is being attempted. The effect of surface tension on AM deposits will be fully characterized and understood for process control. Another research focus addresses the design and manufacture of thermal spray coatings with enhanced wear and fracture resistance for oil and gas drilling operations. The CSM Site will continue to study and design low transformation temperature welding (LTTW) consumables for distortion control and residual stress mitigation control. These programs are expected to lead to the development of fundamental knowledge as well as practical technology. The CSM Site is also pursuing cross university and multi-industry collaboration on intelligent welding, friction stir processing, robotics, advanced neutron and X-rays characterization, and data-driven modeling.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.
