dc.description.abstract80Ni20Cr alloy was manufactured by laser 3D printing technology using two different laser 3D printing routes, namely, layer-layer orthogonal and layer-layer with the same direction, and the microstructure and mechanical properties of 80Ni20Cr alloy were also studied. The results show that the microstructures of alloy components present small lamellar grains and columnar grains, and the columnar grains grow along the path of laser 3D printing route. The composition of the alloy components is Ni-Cr solid solution based Ni solvent. Moreover, the density of 80Ni20Cr alloy manufactured by laser 3D printing is close to the theoretical density of alloy. The porosity of 80Ni20Cr alloy fabricated by laser 3D printing technology using layer-layer orthogonal route is lower than that of layer-layer with the same direction, meanwhile, the average micro-hardness and tensile properties of 80Ni20Cr alloy components using layer-layer orthogonal route are also higher than that of using layer-layer with the same direction, and the tensile strength of alloy reaches up to 410 MPa, the hardness of alloy reaches up to 406 HV0.2.en_AU
