摘要：

Metallographic microscope, XRD, SEM and tensile testing methods were used to explore the influence of 45 degrees cross grating and zig-zag cross grating scanning paths on GH3536 alloy fabricated by laser solid forming (LSF). The results show that the two scanning paths have little effect on the microstructure of GH3536 alloy. The substrate of GH3536 alloy with two scanning paths are y phase. There are two types of carbides, M23C6 and M6C. The heat accumulation of zig-zag cross grating is slightly higher than that of 45 degrees cross grating, resulting in larger porosity and a higher forming height. The tensile properties of GH3536 alloy with two scanning paths are similar. The fracture mode is ductile fracture. The cracks occurs at the carbide, and are mainly transgranular fracture.
