Process parameters and properties of laser powder bed fusion alloys

List of process paramaters and resulting properties of printed samples after laser powder bed fusion. Process parameters include: manufacturer of LPBF equipment, equipment model and laser type of the printer, laser power (P), scan speed (v), nominal powder layer thickness (t), hatch spacing (h), laser beam diameter (spot size (d), focus offset distance of the laser beam, scanning strategy, rotation angle of scanning strategy between layers and the build plate temperature. Information about the post-processing of the alloys was collected as to whether the alloy was heat-treated, heat treatment type, temperature and duration of each heat treatment step. Properties include consolidation, hardness, yield stress, elongation to failure, tensile strength Dataset was collected from peer-reviewed publicaions. Sources of the original data are provided within the datasheet.本数据集收录了激光粉末床熔融（LPBF, Laser Powder Bed Fusion）打印试样的工艺参数及其最终性能数据。工艺参数涵盖：激光粉末床熔融设备制造商、打印机设备型号与激光器类型、激光功率（P）、扫描速度（v）、名义粉末层厚度（t）、Hatch间距（h）、激光束直径（光斑尺寸(d)）、激光束聚焦偏移距离、扫描策略、层间扫描策略旋转角度以及成形基板温度。同时收集了合金材料的后处理信息，包括是否对合金进行热处理、热处理类型、各热处理步骤的温度与时长。测试性能包括致密度、硬度、屈服强度、断后伸长率、抗拉强度。本数据集的原始数据均来自同行评议的公开学术文献，数据表中已标注原始数据来源。
