Data on the material characterization of cast and additively manufactured IN939 subjected to room-temperature low-cycle fatigue load

The original data to the research paper termed "Room-temperature low-cycle fatigue behaviour of cast and additively manufactured IN939 superalloy" are enclosed. Two specimen orientations of L-PBF IN939 - horizontal and vertical, and two thermodynamical states - without subsequent heat treatment (non-treated) and standard aged according to Delargy et al., 1986, were investigated. The paper concerns the low-cycle fatigue performance of cast and additively manufactured IN939 superalloy. It brings a comprehensive account on the damage and deformation behaviour of the tested alloy, combining the test analyses with high-resolution SEM and TEM observations.本研究附上了题为《铸造与增材制造IN939高温合金的室温低周疲劳行为》的学术论文的原始实验数据。本次研究考察了激光粉末床熔融（L-PBF）IN939合金的两种试样取向：水平取向与垂直取向，以及两种热力学状态：未进行后续热处理的未处理态，与按照Delargy等人1986年的标准进行时效处理的状态。本论文聚焦铸造与增材制造IN939高温合金的低周疲劳性能，对受试合金的损伤与变形行为进行了全面阐述，并将实验分析与高分辨率扫描电子显微镜（SEM）、透射电子显微镜（TEM）观测相结合。
