Neutron diffraction was employed to measure internal residual stresses at various locations along stainless steel (SS) 17-4 PH specimens additively manufactured via laser-powder bed fusion (L-PBF). Of these specimens, two were rods (diameter=8 mm, length=80 mm) built vertically upward and one a parallelepiped (8×80×9 mm) built with its longest edge parallel to ground. One rod and the parallelepiped were left in their as-built condition, while the other rod was heat treated. Data presented provide insight into the microstructural characteristics of typical L-PBF SS 17-4 PH specimens and their dependence on build orientation and post-processing procedures such as heat treatment. Data have been deposited in the Data in Brief Dataverse repository (doi:10.7910/DVN/T41S3V).
采用中子衍射法测量通过激光粉末床熔融（L-PBF）增材制造的17-4沉淀硬化不锈钢（SS）试样沿不同位置的内部残余应力。这些试样中，有两根是垂直向上构建的棒材（直径 = 8毫米，长度 = 80毫米），还有一个是最长边平行于地面构建的长方体（8×80×9毫米）。一根棒材和长方体保持其制造后的状态，而另一根棒材进行了热处理。所呈现的数据有助于深入了解典型的L-PBF SS 17-4 PH试样的微观结构特征，以及它们对构建方向和诸如热处理等后处理程序的依赖性。数据已存于《简要数据》数据存储库（doi:10.7910/DVN/T41S3V）。
