Abstract Scope |
Recently, Research on a Layer-by-Layer process rather than the existing casting process is being actively conducted and applied to various industries such as automobiles. Due to environmental and energy efficiency issues, the automotive industry is focusing on reducing the weight of materials. However, the existing method of reducing the thickness has limitations such as decreased stiffness and vibration. In addition, the use of Al alloy, Mg alloy, etc. for weight reduction has a disadvantage of high price. By designing and establishing process conditions for low-Mn added Fe-based lightweight steel with Fe-Mn-Al-C composition, we overcome the high cost of existing alloys like high-Mn added or medium-Mn Fe based steels through the DED process, a representative metal additive manufacturing process. Additionally, we confirmed that the casting material and low-Mn added Fe-based lightweight steel have similar properties. |
