Phase II Lehigh U Site: I/UCRC for Manufacturing and Materials Joining Innovation Center (Ma2JIC)

工业制造的许多重要部件和系统随后在美国基础设施中使用，这些部件和系统需要在制造过程中的某个时候加入。例子包括飞机零部件、桥梁和发电厂，仅举几例。连接过程相当复杂，可能会显著改变用于制造部件的材料的性能，从而影响部件在目标设计寿命内安全运行的能力。安全有效地设计、制造和使用通过连接制造的部件需要整合许多工程学科。不幸的是，目前只有少数几所美国大学可以解决这些挑战，而美国缺乏为解决这些问题而培训的合格工程师。制造和材料联合创新中心(Ma2JIC)就是为了满足这些需求而成立的。由于加入和许多新兴添加剂制造(AM)工艺之间的相似之处，该中心已扩展到包括AM所有Ma2JIC站点的学术研究人员与中心成员密切合作，确定将为成员公司提供改进性能和/或降低与其设计、制造和/或使用的组件相关的成本的方法的研究项目。在所有地点开展的研究项目也是教育下一代训练有素的研究生级别的科学家和工程师的工具，以解决工业界面临的此类专业人员短缺的问题。位于Ma2JIC内的利哈伊大学网站提供建模和电子显微镜等几个不同领域的研究专业知识，并通过其能源研究中心提供与能源行业的强大联系。此外，利哈伊现场的教育目标还扩展到包括本科生在内，通过一门关于材料选择和失效分析的高级顶峰课程，中心成员提供失效部件供学生分析，并担任学生的工业导师。安全和有效地使用通过连接制造的部件需要整合许多学科，并开发先进的表征和建模工具。目前只有为数不多的几所美国大学能够解决这些挑战，而且缺乏为解决这些问题而培训的合格工程师。制造和材料联合创新中心(Ma2JIC)就是为了满足这些需求而成立的。由于加入和许多添加剂制造(AM)工艺之间的相似之处，该中心已扩展到包括AM所有Ma2JIC站点的学术研究人员与中心成员密切合作，确定将为成员公司提供改进性能和/或降低与其设计、制造和/或使用的组件相关的成本的方法的研究项目。研究将在利哈伊工地的几个不同领域进行，这些领域已经由工业界和学术合作伙伴共同确定，包括应力消除开裂、焊缝的蠕变断裂、堆焊层、不同的金属焊缝和高强度钢。这项研究将把相变的基本原理与最先进的建模工具和先进的微结构表征技术相结合，为成员提供与其使用和/或制造的组件相关的信息，以提高性能和/或降低成本。在Ma2JIC所有地点开展的研究项目也是教育下一代训练有素的科学家和工程师的工具，以解决工业界面临的这类专业人员短缺的问题。这一目标将在利哈伊现场扩展到包括本科生在内，通过关于材料选择和失效分析的高级顶峰课程，中心成员提供故障部件供学生分析，并将担任工业导师。学生将把他们的发现提交给中心成员，并为每半年举行一次的中心会议提供海报。该计划将增加中心会员的价值，并改善本科生的学习体验。

Many important components and systems that are fabricated by industry and subsequently used within the US infrastructure require joining at some point within the manufacturing process. Examples include aircraft parts, bridges, and power generation plants, just to name a few. Joining processes are quite complex and can significantly alter the properties of the materials used to create the component, thus affecting the ability of the component to operate safely over the targeted design life. Safe and effective design, fabrication, and use of components manufactured by joining requires integration of many engineering disciplines. Unfortunately, there is currently only a handful of US universities for solving these challenges, and there is a shortage of qualified engineers being trained in the US to address these issues. The Manufacturing and Materials Joining Innovation Center (Ma2JIC) was established to fulfill these needs. Due to the similarities between joining and many emerging Additive Manufacturing (AM) processes, the Center has expanded to include AM. The academic researchers at all the Ma2JIC sites work closely with Center members to identify research projects that will provide member companies with methods for improving the performance and/or reducing the costs associated with components they design, manufacture, and/or use. The research projects conducted at all the sites also serve as vehicles for educating the next generation of highly trained graduate-level scientist and engineers in order to address the shortage of such professionals faced by industry. The Lehigh University site within Ma2JIC provides research expertise in several distinct areas such as modeling and electron microscopy, and also provides a strong link to the energy industry through their Energy Research Center. In addition, the educational goal is extended at the Lehigh site to include undergraduate students through a senior capstone course on Materials Selection and Failure Analysis in which Center members provide failed components for analysis by the students and serve as industrial mentors to the students. Safe and effective use of components manufactured by joining requires integration of many disciplines and the development of advanced characterization and modeling tools.

The academic researchers at all the Ma2JIC sites work closely with Center members to identify research projects that will provide member companies with methods for improving the performance and/or reducing the costs associated with components they design, manufacture, and/or use. Research will be conducted at the Lehigh site in several different areas that have been identified jointly by industry and the academic partners, including stress relief cracking, creep-rupture of welds, weld overlay coatings, dissimilar metal welds, and high strength steels. The research will combine basic principles of phase transformations with state-of-the-art modeling tools and advanced microstructural characterization techniques to provide members with information for improving the performance and/or reducing costs associated with components they use and/or manufacture. The research projects conducted at all the Ma2JIC sites also serve as a vehicle for educating the next generation of highly trained scientist and engineers in order to address the shortage of such professionals faced by industry. This goal will be extended at the Lehigh site to include undergraduate students through the senior capstone course on Materials Selection and Failure Analysis in which Center members provide failed components for analysis by the students and will serve as industrial mentors. The students will submit their findings to the Center members and provide posters for the semi-annual Center meetings. This program will add value to Center memberships and improve the learning experience for undergraduate students.
