核能和航空航天应用对安全性至关重要，需要高质量的金属部件。这些部件故障的成本远远超过修理或更换的成本。因此，有必要在制造和使用过程中跟踪部件几何形状的关键位置处的材料特性的演变，以避免过早失效。数字线程/双胞胎（DTh/DT）范式显示了其通过监控组件生产与组件交互的能力。DTh的这种能力可以通过生成称为材料护照（MP）的组件特定的唯一标识文档来进一步扩展。除了存储制造历史和检查记录外，MP还可用于指示剩余使用寿命估计，以指导组件的可回收性/可重复使用性。DTh和相应MP的结构取决于几个因素。本文概述了DTH/DT的性质为制造业的基础上，在各自的计算框架和类型的材料采购规范系统中实施的材料属性定义的长度尺度。然后，可能的结构，实现MP，使预测性维护和循环经济的意义和挑战进行了讨论。初步讨论表明，实施组件特定DTH，包括所有阶段的制造结合生成的摘要和详细的MP在每个阶段，提高数据存储和可访问性MP和DTH的预测性维护能力。最后，简要介绍了MP和DTH中使用的标准的概况。
Nuclear and aerospace applications are critical to safety that demand quality metallic components. The cost of failure in these components far exceed that of repair or replacement. Thus, it is necessary to track the evolution of material properties at critical locations of the component geometry during manufacturing and in-service to avoid premature failures. The digital thread/twin (DTh/DT) paradigm shows promise for its ability to interact with components by monitoring their production. This capability of the DTh can be further extended by generating component specific unique identification document called material passport (MP). In addition to storing the manufacturing history and inspection records, the MP can be used to indicate remaining useful life estimations to guide component recyclability/reusability. The structure of the DTh and the corresponding MP depends on several factors. This article presents an overview of the nature of DThs/DTs for manufacturing based on the lengthscale of material property definitions employed in respective computational framework and the type of material purchase specification system implemented in the industry. Then, the possible structure, significance and challenges of realizing MPs that enable predictive maintenance and circular economy are discussed. The preliminary discussions indicate that the implementation of component specific DThs encompassing all the stages of manufacturing in conjunction with the generation of summary and detailed MPs at every stage improves data storage and accessibility within MPs and predictive maintenance capabilities of DThs. Finally, the landscape of standards used in MPs and DThs is addressed briefly.
