Embodiment
[0041] Gas atomized powders containing 6.43%, 8.32%, and 10.40% of Al in mass % and the remainder containing Fe and unavoidable impurities were produced and classified into 10 μm to 53 μm. Gas atomization is carried out in the following manner: high-frequency dissolution is performed in vacuum, the molten alloy is dropped from a nozzle with a diameter of 5 mm under the crucible, and sprayed with high-pressure argon gas. Using this as a raw material powder, using a three-dimensional lamination molding machine (manufactured by EOS Corporation, EOS-M290), using S45C as a base plate, a powder bed method was used to produce a width of 10mm, a length of 120mm, and a stacking height of 20mm by high-speed melting and rapid solidification by laser irradiation. The elongated shape of the body ( figure 1 ). The lamination thickness of each layer was 40 μm, and the irradiation direction was rotated by 67° for each layer. The diameter of the laser beam is about 0.1mm, and the laser outpu...
