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

许多由工业制造并随后在美国基础设施中使用的重要组件和系统需要在制造过程中的某个点进行连接。例子包括飞机零件、桥梁和发电厂，仅举几例。连接过程非常复杂，并且可能会显著改变用于创建组件的材料的特性，从而影响组件在目标设计寿命内安全运行的能力。通过连接制造的部件的安全有效的设计、制造和使用需要许多工程学科的集成。不幸的是，目前只有少数几所美国大学能够解决这些挑战，并且美国缺乏合格的工程师来解决这些问题。制造和材料联合创新中心（Ma 2 JIC）的成立就是为了满足这些需求。由于连接和许多新兴的增材制造（AM）工艺之间的相似性，该中心已扩大到包括AM。所有Ma 2 JIC站点的学术研究人员与中心成员密切合作，以确定研究项目，这些项目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。在所有地点进行的研究项目也是教育下一代训练有素的研究生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问题。Ma 2 JIC内的利哈伊大学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有力联系。此外，教育目标在利哈伊网站扩展到包括本科生通过高级顶点课程材料选择和故障分析，其中中心成员提供失败的组件由学生进行分析，并作为工业导师的学生。 安全有效地使用通过连接制造的组件需要集成许多学科并开发先进的表征和建模工具。目前只有少数几所美国大学能够解决这些挑战，并且缺乏合格的工程师来解决这些问题。制造和材料联合创新中心（Ma 2 JIC）的成立就是为了满足这些需求。由于连接和许多增材制造（AM）工艺之间的相似性，该中心已扩展到包括AM。所有Ma 2 JIC站点的学术研究人员与中心成员密切合作，以确定研究项目，这些项目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。研究将在Lehigh现场进行，这些研究将在工业界和学术界合作伙伴共同确定的几个不同领域进行，包括应力消除裂纹、焊缝蠕变断裂、堆焊层、异种金属焊缝和高强度钢。该研究将结合联合收割机相变的基本原理与最先进的建模工具和先进的微观结构表征技术，为成员提供信息，以提高性能和/或降低与他们使用和/或制造的组件相关的成本。在所有Ma 2 JIC站点进行的研究项目也可以作为教育下一代训练有素的科学家和工程师的工具，以解决行业面临的此类专业人员短缺问题。这一目标将在利哈伊网站扩展到包括本科生通过材料选择和故障分析的高级顶点课程，其中中心成员提供失败的组件供学生分析，并将作为工业导师。学生们将把他们的发现提交给中心成员，并为每半年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.
