Impact test data for A533B ar material at -50 °C and a notch impact energy of 67 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.结构部件评估网络（NESC）协调了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项目聚焦于将实验室试样的断裂韧性数据迁移应用于评估承受异常与正常载荷瞬态工况的反应堆压力容器完整性。该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计划所开展的双轴特性测试计划的核心内容。在此背景下，JRC针对A533B型铁素体钢在-90℃至80℃的温度区间内开展了冲击试验与拉伸试验。
