田纳西大学诺克斯维尔分校(UTK)的能源应用集成材料联合科学中心(CIMJSEA)致力于缩小材料开发和焊接性之间的差距，开发基于科学的方法来评估各种材料的材料焊接性和可焊性，范围从纳米到毫米长，同时教育和开发加入工程师和科学家的新一代材料。该计划旨在确定与加盟相关的关键挑战，以确保研究项目的一致性，并探索专门为制造量身定做的材料的开发。研究将与未来和现有制造业相关。UTK SITE的专长包括材料开发、横切能力，包括多尺度表征和建模，以及添加剂制造的一个新的推动领域。后者有可能在多种方面造福社会，包括减少稀缺和日益减少的原材料。熟练的新工程师将通过逐层建造而不是减法进行设计，允许在设计复杂性方面有无限的可能性。该计划将通过乐高联赛组织和指导年轻学生，在校园内建立和维护开放的3D打印实验室，并通过支持高级Capstone设计活动，覆盖从小学到小学的大年龄段的学生。UTK工厂的技术努力将通过跨学科研究促进焊接、材料连接和添加剂制造技术的创新，将设计、机器人和自动化、过程控制、材料科学、先进表征和高性能计算建模结合在一起。UTK现场的研究包括大规模添加剂制造和聚合物基复合材料与金属的连接。与现有的联合技术相结合，UTK工厂的努力将创造一个加速混合材料系统开发的环境，并将专注于扩大与汽车、航空航天和能源应用相关的经过验证的实验室开发。这项研究将促进与这些组成材料之间界面的热机械-化学性质相关的科学发现，并将应用先进的原位和非原位表征技术来了解循环热和应力加载、残余应力发展和微观结构演变等问题。最终结果将是基础研究在联合和添加制造的十字路口源源不断地涌现。

The University of Tennessee, Knoxville (UTK) site of the Center for Integrative Materials Joining Science for Energy Applications (CIMJSEA) seeks to close the gap between material development and weldability and to develop scientifically based methodologies for assessing material weldability and joinability that span from the nanometer to millimeter length scales over a wide variety of materials, while educating and developing a new generation of materials joining engineers and scientists. The program seeks to identify
 critical joining-related challenges to ensure alignment of research projects and to explore
the development of materials specifically tailored for manufacturing. Research will be relevant 
to the future and existing manufacturing. The UTK site specialties include materials development, crosscutting capabilities that include multi-scale characterization
and modeling, as well as a new thrust area in additive manufacturing. The latter has the potential to benefit society in a multitude of ways including reducing scarce and dwindling raw materials. Proficient new engineers will design by building layer-by-layer instead of by subtraction, allowing for unlimited possibilities in design complexity. The program will reach out to a large age span of students, from elementary school onwards, by organizing and coaching younger students through LEGO league competitions, establishing and maintaining open 3D printing laboratories on campus, and by supporting Senior Capstone Design activities. Technical efforts of the UTK site will foster innovations in welding, materials joining and
additive manufacturing technologies through interdisciplinary research, bringing together design, robotics and automation, process control, materials science, advanced characterization and high-performance computational modeling. The research at the UTK site includes large-scale additive manufacturing and joining polymer matrix composites
to metals. In combination with existing joining technologies the efforts of the UTK site will create an environment where the development of hybrid material systems is accelerated and will be focused
on the scale-up of proven laboratory developments relevant to automotive, aerospace, and energy applications. The research will promote scientific discoveries related to the thermo-mechanical-chemical properties of interfaces between these constituent materials and advanced in situ and ex situ characterization techniques will be applied to understand issues such as cyclic thermal and
stress loading, residual stress development, and microstructural evolution. The end result will be a steady flow of fundamental research at the crossroads of joining and additive manufacturing.
