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(Ma2JIC)致力于基础设施重建和创新材料在现代制造业中的应用，这是国家利益的问题。Ma2JIC中心在大学和工业合作伙伴之间建立了一个环境，促进了材料连接和添加剂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平台。科罗拉多州矿业学院(CSM)自成立以来，凭借其在能源、航空航天、石油天然气和制造业的创新焊接材料设计和制造、焊接和连接工艺创新、焊接材料表征和添加剂制造方面的独特专业知识和实验室设施，为该中心提供了补充。CSM网站将寻求加强与其他中心网站的合作，共同发展与焊接、连接和制造行业、大大小小的国家实验室和政府机构的合作。该中心的优势是该集团有能力缩小材料开发和制造业所用材料的焊接性之间的差距，并从所有这些令人惊叹的协同中获得最终的社会利益。Ma2JIC中心在工艺创新、材料性能、添加剂制造、焊接性测试和评估方面的研究将发展对材料四面体-“Processing-Microstructure-Properties-Performance”.所描述的基本理解CSM现场研究人员正在研究激光-粉末熔化AM产品的GTA和激光焊接性的基本方面，激光-粉末熔化和定向能沉积AM产品的凝固行为，以及用于电子束自由形状制造产品(包括金属基复合材料)微观结构优化的填充金属开发。人们正在尝试将反应合成粉末加入管状金属丝中，用于基于激光和基于电子束的添加剂制造。表面张力对AM沉积的影响将得到充分的表征和理解，以便进行工艺控制。另一个研究重点涉及用于石油和天然气钻井作业的热喷涂涂层的设计和制造，该涂层具有增强的耐磨性和抗裂性。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网站还寻求在智能焊接、摩擦搅拌处理、机器人、先进的中子和X射线表征以及数据驱动建模方面的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智力优势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.
