Impact test data for A533B wm material at -50 °C and a notch impact energy of 29 J

The Network for Evaluating Structural Components (NESC) coordinated extensive materials testing and fracture analyses performed by a group of twenty European organizations. The NESC-IV project addressed the transferability of fracture toughness data from laboratory specimens to applications that assess the integrity of reactor pressure vessels subjected to upset and normal loading transients. The coordinated experimental and analytical program drew from major elements of the biaxial features testing program conducted by the Heavy Section Steel Technology Program at the Oak Ridge National Laboratory. In this context, the JRC performed impact and tensile tests in the temperature range -90 to 80ºC on type A533B ferritic steel.结构组件评估网络（Network for Evaluating Structural Components, NESC）协调了由20家欧洲机构开展的大规模材料测试与断裂分析工作。NESC-IV项目旨在解决断裂韧性数据从实验室试样向反应堆压力容器完整性评估应用的迁移问题，该类应用需经受异常与正常载荷瞬态工况。本次协同实验与分析计划借鉴了橡树岭国家实验室厚截面钢材技术项目所开展的双轴特性测试计划的核心内容。在此背景下，联合研究中心（Joint Research Centre, JRC）针对A533B型铁素体钢开展了温度范围为-90℃至80℃的冲击试验与拉伸试验。
