Research Data on the Effect of NbC Inoculants on the Elastic and Microstructural Evolution of LBP-DED IN718

A phase analysis was carried out through XRD and TEM-EDS. XRD was completed using a Bruker D8 X-ray diffractometer and DSC was performed on a Netzsch 404 calorimeter with cylindrical specimen of a diameter of 5 mm and a thickness of 1.0 mm. TEM was performed on an FEI™ Tecnai Osiris TEM operated at 200 kV. A Zeiss Gemini SEM 450 equipped with an Oxford Instruments Symmetry EBSD detector and an Oxford Instruments X-MaxN 50 detector was used for microstructure and texture analysis. RUS was used to determine the elastic constants and calculate elastic properties. The oxidation performance was assessed using a Setaram Instruments Setsys Evolution TGA.

本研究通过X射线衍射（XRD）与透射电子显微镜-能谱仪（TEM-EDS）开展物相分析。X射线衍射测试采用布鲁克D8 X射线衍射仪完成，差示扫描量热法（DSC）测试使用耐驰404量热仪进行，试样为直径5 mm、厚度1.0 mm的圆柱状样品。透射电子显微镜测试采用FEI™ Tecnai Osiris透射电镜完成，测试加速电压设置为200 kV。采用配备牛津仪器Symmetry电子背散射衍射（EBSD）探测器与牛津仪器X-MaxN 50能谱探测器的蔡司Gemini SEM 450扫描电镜，开展微观组织与织构分析。采用共振超声光谱法（RUS）测定弹性常数并计算弹性性能。氧化性能评估采用塞塔拉姆Setsys Evolution热重分析仪（TGA）完成。
