Abstract：GH3536 alloy exhibits stable performance at elevated temperatures and is extensively utilized in high-temperature resistant components, including eddy current devices and engine blades. In this research, GH3536 alloy blocks were fabricated using laser powder bed fusion with partitioned block rotating scanning. The surface microstructure of the alloy was analyzed through scanning electron microscope and electron backscatter diffraction. Additionally, the mechanical properties and microhardness of the printed alloy were evaluated at room temperature. The results indicate that GH3536 alloy exhibits a limited number of pores and microcracks. Furthermore, a distinct microstructural difference is observed between the horizontal surface (XOY plane) and the constructed surface (XOZ plane). The XOY plane displays parallel scanning tracks, whereas the XOZ plane reveals melt pools, and the grains are fine and the dislocation density is relatively high at the melt pool boundaries. The room temperature tensile strengths of the alloy parallel to the XOY direction and the XOZ direction are 878 MPa and 762 MPa, respectively, and the elongation rates are 32% and 42%, respectively. There are a large number of small dimples at the tensile fracture. The microhardness (HV0.2) for the XOY and XOZ planes are 308 and 299, respectively.
