Abstract Fe-Mn-Al-C lightweight steels exhibit low density and good mechanical property, making them suitable for lightweight and high strength material needed in aerospace, automotive energy, and deep-sea exploration. Nevertheless, as a crucial element for its weight reduction and performance control, the large addition of Al will lead to the difficulty of traditional casting, which limits its application in complex-shaped components. Therefore, laser solid forming additive manufacturing technology was used to tackle the aforementioned problems by exploiting its high forming freedom and micro-molten pool metallurgical properties. Taking Fe-30Mn-9.5Al-2C as the research object, the optimal combination of process parameters was explored by orthogonal test, and the phase composition and microstructure evolution under the optimal process parameters were studied. The results show that under the optimal process parameters, the microstructure is composed of austenite, a small amount of ferrite and κ-carbide, and the hardness is up to 539HV. The research results can guide the manufacturing of Fe-Mn-Al-C steel via laser solid forming.

Key words： Fe-Mn-Al-C additive manufacturing process parameter microstructure hardness
