| Abstract | A Ni-based superalloy was fabricated by laser additive manufacturing technology (LEN98M) and traditional directional solidification (DZ98M). The solidification morphology, microstructures, elements segregation were investigated by optical microscope (OM), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), electron microprobe (EPMA) and differential thermal analysis (DTA). The results show that the primary dendrite arm spacing of the LEN98M alloy is 70 mu m and only as 1/5 of that of the DZ98M alloy. There is serious segregation of alloying elements in the range of dendrite scale. The morphology of gamma' phase is irregular and no precipitation of carbides is observed in LEN98M alloy. Small gamma/gamma' eutectic which are more dispersed occur in interdendritic regions. |
