I/UCRC Phase II: Collaborative Research: CIMJSEA Phase II Proposal

俄亥俄州立大学制造与材料连接创新中心（Ma2JIC）前身为能源应用综合材料连接科学中心（CIMJSEA），该中心与其合作大学一起建立了项目，以推进材料连接科学和技术，并将其应用于先进制造。该中心的使命是1)缩小材料开发与可焊性之间的差距，2)开发基于科学的方法来评估材料的可焊性/可接合性，跨度为nm到mm长度尺度，3)开发新一代材料，加入工程师和科学家。材料连接是保持美国制造业领导地位的关键技术。这项技术几乎影响了美国工业的每一个领域。该中心旨在确定对这些行业至关重要的项目，并为学生提供科学和工程技能，使他们能够为社会做出贡献。项目包括焊接工艺、材料科学、设计和服务健康等方面。有一个强大的重点是计算工具的发展，促进传统和先进材料的连接。该中心开展了许多项目，分为五个技术重点领域，即1)材料性能，2)可焊性测试与评估，3)建模，4)工艺开发与创新，5)增材制造。材料性能推力领域的项目涉及与传统和先进材料相关的可焊性问题，特别强调提高服务性能，延长关键部件的使用寿命，降低制造成本。可焊性测试和评估重点领域旨在开发测试方法，以验证新材料和工艺，并为材料生产商提供允许开发“可焊”材料的输入。建模推力领域正在开发综合计算材料工程（ICME）技术，通过严格考虑材料和工艺之间的复杂相互作用来预测焊接结构的性能。工艺开发和创新重点领域评估现有的焊接工艺，并寻求确定代表传统工艺改进的新焊接工艺。最后，增材制造重点领域包括旨在更好地了解金属沉积过程并确定该技术应用的项目。这些项目的结果既影响现有材料的当前应用，也影响先进材料在广泛工业应用中的潜在使用。

The Manufacturing and Materials Joining Innovation Center (Ma2JIC) - formerly Center for Integrative Materials Joining Science for Energy Applications (CIMJSEA) at Ohio State University and in conjunction with its partner universities has established programs to advance the science and technology of materials joining as it applies to advanced manufacturing. The mission of the center is to 1) close the gap between material development and weldability, 2) develop scientifically-based methodologies for assessing material weldability/joinability that span nm to mm length scales, and 3) develop a new generation of materials joining engineers and scientists. Materials joining is a critical enabling technology essential to maintaining US leadership in manufacturing. This technology impacts virtually every segment of US industry. The center seeks to identify projects that are critical to these industries and provide students with the scientific and engineering skills that will allow them to contribute to society. Projects include aspects of welding processes, materials science, design, and fitness-for-service. There is a strong focus on the development of computational tools that facilitate the joining of conventional and advanced materials.The center conducts a number of projects that are organized into five technology thrust areas, namely 1) Material Performance, 2) Weldability Testing and Evaluation, 3) Modeling, 4) Process Development and Innovation, and 5) Additive Manufacturing. Projects within the Materials Performance thrust area involve weldability issues associated with conventional and advanced materials, with particular emphasis on improving service performance, extending the lifetime of critical components, and reducing manufacturing costs. The Weldability Testing and Evaluation thrust area seeks to develop testing methods to validate new materials and processes and provide input to material producers that allows the development of "weldable" materials. The Modeling thrust area is developing integrated computational materials engineering (ICME) techniques that predict the performance of welded structures by rigorously considering the complex interactions between materials and processes. The Process Development and Innovation thrust area evaluates existing welding processes and seeks to identify new welding processes that represent improvements over conventional processes. Finally, the Additive Manufacturing thrust area consists of projects that seek to develop a better fundamental understanding of metal deposition processes and to identify applications of this technology. The results of these projects influence both current application of existing materials and potential use of advanced materials in a wide range of industrial applications.
