聚变反应堆所需的设计数据的特点是材料的多样性和这些反应堆中发现的装载情况的复杂性。此外，先进的制造技术，如热等静压，设想用于制造单层和多层容器内组件，可以显着改变当前设计规则所编写的原始材料属性。因此，必须为聚变反应堆产生额外的材料特性，并制定新的结构设计规则。本文回顾了ITER和DEMO产生的一些材料特性数据，并给出了如何将这些数据转换为设计标准的例子。特别是，它给出了316LN-IG和改性9 Cr-1 Mo钢和CuCrZr合金的性能的具体实例。这些包括确定拉伸、蠕变、等应变、疲劳和蠕变-疲劳曲线，并对其进行分析和转换为设计极限。
Design data needed for fusion reactors are characterized by the diversity of materials and the complexity of loading situations found in these reactors. In addition, advanced fabrication techniques, such as Hot Isostatic Pressing, envisaged for fabrication of single and multilayered in-vessel components, could significantly change the original materials properties for which the current design rules are written. As a result, additional materials properties have had to be generated for fusion reactors and new structural design rules formulated. This paper recalls some of the materials properties data generated for ITER and DEMO, and gives examples of how these are converted into design criteria. In particular, it gives specific examples for the properties of 316LN-IG and Modified 9Cr–1Mo steels, and CuCrZr alloy. These include, determination of tension, creep, isochronous, fatigue, and creep–fatigue curves and their analysis and conversion into design limits.
