目前正在考虑两种铜基合金作为ITER导流器、限制器和第一壁等离子体组件（pfc）的散热材料。在脉冲操作期间，这些合金将受到循环应力和稳定载荷的影响：预计疲劳、蠕变和蠕变-疲劳联合效应将是限制这些全氟碳化物使用寿命的重要因素，特别是铜合金组件。因此进行了广泛的热物理和机械性能测量，包括在真空下，以提供这些重要合金的材料特性，添加到ITER材料数据库并指导未来的设计工作。
Two copper-based alloys are currently under consideration as the heat sink material for the divertor, limiter and first-wall plasma facing components (PFCs) of ITER. During pulsed operation, these alloys will be subjected to cyclic stresses and periods of steady loading: it is anticipated that fatigue, creep and combined creep-fatigue effects will be important in limiting the operational lifetime of these PFCs, in particular the copper alloy components. A wide range of thermophysical and mechanical properties measurements have therefore been made, including under vacuum, in order to provide material characterisation of these important alloys, to add to the ITER materials database and to guide future design efforts.
