Impact test data for A533B wm material at -25 °C and a notch impact energy of 54 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家欧洲机构共同开展的大规模材料测试与断裂分析工作。NESC-IV项目旨在研究断裂韧性数据从实验室试样到反应堆压力容器完整性评估场景的可转移性，这类压力容器需经受异常与正常载荷瞬变工况。这项协同开展的实验与分析项目，借鉴了橡树岭国家实验室厚截面钢材技术计划所实施的双轴特性测试项目的核心内容。在此背景下，联合研究中心（Joint Research Centre，JRC）针对A533B铁素体钢开展了温度区间为-90℃至80℃的冲击试验与拉伸试验。
