Impact test data for A533B wm material at -35 °C and a notch impact energy of 20 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.

评估结构部件网络（NESC）协调了由20家欧洲机构组成的团队开展的大量材料测试与断裂分析工作。NESC-IV项目旨在研究断裂韧性（fracture toughness）数据从实验室试样到实际应用场景的可迁移性——这些应用场景用于评估反应堆压力容器在瞬态扰动载荷与正常载荷下的完整性。该协同实验与分析项目借鉴了橡树岭国家实验室（Oak Ridge National Laboratory）重型截面钢技术项目（Heavy Section Steel Technology Program）开展的双轴特性测试项目（biaxial features testing program）中的核心要素。在此背景下，联合研究中心（JRC）对A533B型铁素体钢在-90℃至80℃温度范围内开展了冲击试验（impact tests）与拉伸试验（tensile tests）。
