Dataset values of Instrumented Charpy V-notch impact tests (ICITs) of base material (BM), heat affected zone (HAZ) and fusion zone (FZ) of the electron beam welded (EBW) joints of S960M high strength steel (HSS)

-High-strength structural steel S960M was welded using electron beam welding to analyse the weldability of steel through various metallurgical and mechanical tests. -The instrumented Charpy V-notch impact testing was employed because it offers more precise information on the fracture process and the material's ductile/brittle behavior than the traditional Charpy V-notch impact test, which can only provide the total energy absorbed during the fracture. -Materials comprising measurement data from instrumented Charpy V-notch impact tests (load vs. time data) of base material (BM), heat-affected zone (HAZ), and fusion zone (FZ) (5 samples of test data for each mentioned part, Zip files) -The Charpy impact testing equipment was linked to a digital signal oscilloscope for real-time data collecting using the strain gauge measuring method. The load-time graph was generated, and the fracture process's characteristic points were determined (the start of the plastic strain, the maximal force, and the start and end of the unstable crack propagation). -From the load-time graph, the force-displacement graph can be calculated. Until the maximum force, the under the curve was considered as the absorbed energy for crack initiation (Wi), whereas the rest for crack propagation (Wp). -The Charpy impact test results serve as the foundation for comparing fracture toughness, which is one of the most difficult issues.采用电子束焊接工艺对高强度结构钢S960M进行焊接，通过多种冶金与力学试验分析该钢材的焊接性能。 相较于仅能测得断裂过程中总吸收能量的传统夏比V型冲击试验，本研究采用示波夏比V型冲击试验（Instrumented Charpy V-notch Impact Test），因其可提供关于断裂过程及材料韧脆性行为的更精准信息。 本数据集包含母材（Base Material, BM）、热影响区（Heat-Affected Zone, HAZ）及熔合区（Fusion Zone, FZ）的示波夏比V型冲击试验测量数据（载荷-时间数据），上述每个区域均提供5组试验数据，以压缩包（Zip files）形式存储。 夏比冲击试验设备通过应变片测量法连接至数字信号示波器，以实现实时数据采集；由此生成载荷-时间曲线，并确定断裂过程的特征点（塑性应变起始点、最大载荷点以及不稳定裂纹扩展的起始与终止点）。 可通过载荷-时间曲线计算得到力-位移曲线。最大载荷点之前的曲线下面积被视为裂纹萌生吸收的能量（Wi），剩余部分则为裂纹扩展吸收的能量（Wp）。 夏比冲击试验结果可作为比较断裂韧性的基础，而断裂韧性研究是材料力学领域的难点问题之一。
