PartGeometry_17-4PHSS&AlSi10Mg

This dataset contains experimental data associated with the fatigue behavior of laser powder bed fused (L-PBF) AlSi10Mg and 17-4 PH stainless steel parts with different geometries and thicknesses/sizes. The dataset includes raw fatigue test data, X-ray computed tomography (XCT) data for volumetric defect characterization, and fracture-surface images from failed specimens. The data cover wall, small block, and large block geometries with three different thicknesses/sizes for each geometry. The dataset is provided to facilitate further analysis of geometry and size effects on fatigue behavior, defect characterization, data validation, and the development of predictive models for L-PBF materials.本数据集包含与不同几何形状及厚度/尺寸的激光粉末床熔融（L-PBF）AlSi10Mg与17-4 PH不锈钢构件的疲劳行为相关的实验数据。数据集涵盖原始疲劳试验数据、用于体缺陷表征的X射线计算机断层扫描（XCT）数据，以及失效试样的断口图像。该数据集覆盖壁形、小块体及大块体三种几何构型，每种构型对应三种不同的厚度/尺寸参数。本数据集的发布旨在为疲劳行为的几何与尺寸效应分析、缺陷表征、数据验证，以及激光粉末床熔融材料预测模型的开发等相关研究提供便利。
